Advanced Frequency Control 
Expertise from the World Leader 

At Fox

,

we pride ourselves on offering 

the world's broadest range of standard, stocked, 
off-the-shelf crystals and oscillators. We also pride
ourselves on knowing what the market needs. 
And we understand that, more and more, your
applications may require a frequency control device
with characteristics or capabilities that are not met
by our standard offerings. That's why we've
developed the Fox Customer Technology Center
(CTC)…as a resource for your special needs. 
Our new CTC is designed specifically to deliver
cost-effective, fast-turn solutions to highly
application-specific requirements for crystals,
oscillators, TCXOs, VCXOs and OCXOs.

From tweaks to full custom

Your custom frequency control need may be for 
a slight modification to anexisting product…
a significant variation of a current product…or 
an entirely new concept never before offered, but
just what you need for your unique application.
Whatever it takes,  the FOX CTC is prepared to
tackle it. We'll evaluate your need and provide 
a candid response on what it will take to meet 
that need. And, if we simply can't do it, we'll 

tell you that, too…and perhaps suggest 
another solution to the problem. Our application
engineers are skilled at creating just the right
solutions. If your application warrants it, we'll 
send a FOX FAE to your site to discuss the
situation with you in person.

The Fox CTC has already proven to be a
tremendous success: several innovative products
have already been developed by the CTC, 
including a 77 MHz TCXO, which was designed,
developed, produced, tested and shipped in a
matter of days…rather than the four months
quoted by our competitors!!

Engineered solutions for 

your application

At the heart of the Fox CTC is a powerful, focused
engineering capability, representing an integration
and expansion of our design engineering and
customer support resources, and a significantly
expanded Field Application Engineering staff. 
The CTC specializes in the development of TCXOs,
VCXOs and OCXOs over a wide range of
frequencies and output structures not previously
addressed. The CTC also employs patented

technology for oscillator and RF applications up to
1.4 GHz, opening up new possibilities for highly 
engineered telecom and fiber optic products.

The CTC is supported by a newly formed 
Design Central, comprising the Fox's DEN (Design
Engineering Network) and the Fox Customer
Application Team (CAT). The latter is a dedicated,
multi-discipline team consisting of the primary
customer service person, technical supervisor,
design engineer and marketing person serving 
that particular customer. On the production side,
the CTC has extensive manufacturing tools at its
disposal, including an expanded range of thick 
and thin film, laser, pick and place, wire bonding
and wafer handling processes.

Our CTC is

your

resource!

No matter how unique your frequency control need
may be, chances are high that it can be met at the
Fox Customer Technology Center. Call us with 
your problem…or visit our CTC website at

foxonline.com/ctc

…and we'll provide the solution!

DISTRIBUTOR BRIEFING

The Fox Distribution Program includes all of the Fox Part Numbers identified as DISTRIBUTOR STOCKING
STANDARDS plus all of our JITO-2 product line.  Fox franchised distributors maintain inventory of the
STANDARDS to assure a constant supply to customers who design these items into their products.  Of course,
JITO-2 products are not maintained in inventory as they are 'built to order and schedule' for JIT delivery.

This STANDARDS PROGRAM is formalized in our distributor relationship and in our Contract Manufacturing
relationships, providing maximum global flexibility to our OEM customers.  Design engineers can be confident
that a STANDARD oscillator or crystal will be available for future manufacturing needs.  A check with the Fox
website will reveal current address and phone number information for all of the authorized distributors in your
area.   The feature "StockCheck" on Fox's home page (

www.foxonline.com

)  may be used to confirm

distributor inventory.  Fox global distributors may have regional marketing centers in certain areas of the world,
easily located through the distributors' website.

FOX Electronics - The Leader in Radio Frequency Crystal Oscillator

Radio Frequency Crystal Oscillators

The RFXO Family

 of Oscillators was developed by Fox Electronics Inc. for SONET/SDH/ATM/WAN applications. By combining 

a proprietary ASIC architecture with our advanced quartz technologies, these RFXOs are able to generate very clean output 
frequencies. This exclusive combination of radio frequency control technologies enables these RFXOs to deliver the optimum 

cost-to-performance ratio in the industry for RF applications. See us at

 Electronica 2002.

RFXO Description:

 The RFXO family of Oscillators is an ASIC-driven crystal-based line of frequency control products. These RFXOs are 
available as standard Crystal Oscillators (XOs) or Voltage Controlled Crystal Oscillators (VCXOs) with frequencies from 
600MHz to 1.25GHz. The RFXO family of products generates an output at the frequency of operation (fo) with low jitter 
and phase noise in the frequency domain. Low clock jitter is essential to achieve a low bit error rate in optical data 
communications and also allows for full use of the allotted bandwidth. This makes the RFXO ideally suited for the next 
generation of low jitter clocks and data streams for SONET/SDH applications.

Fox filters offer excellent features such as sharp cut off characteristics,
low loss and high stability over a wide temperature range which are
superior to LC Filters and Ceramic Filters.

The basic building block for all custom built Fox filters is the two-
pole monolithic filter available in standard package as shown.  Two-
pole monolithic filters are cascaded to produce four, six and eight
pole filter responses with the addition of coupling capacitors
between two-pole sections.  Standard Fox filters are available with
center frequencies from 10.7 MHz to 90 MHz, and from two to
eight poles.

For custom made filters, please specify the following:
•  Holder Size
•  Nominal  Frequency
•  Pass Bandwidth

Note:  45F Series 45.000 MHz fundamental is a special filter designed for mobile
radio and cellular phone applications.

•  Insertion Loss
•  Attenuation
•  Spurious Response

•  Ripple
•  Terminating Impedance
•  Operating Temp. Range

Figure 3

Of the various elements, the "AT" cut has become the
most popular as it is available at relatively high frequencies,
exhibits excellent frequency vs temperature stability and
is widely available at reasonable cost. 

 

The frequency vs.

temperature capabilities of the "AT" cut crystal unit are
illustrated in 

Figure 4

.

Figure 4

Fundamental vs. Overtone

This is of concern primarily when specifying the "AT"
cut crystal unit.  These units increase in frequency as the
thickness of the resonator plate is diminished.  At some
point, typically around 30MHz, the plate becomes too
thin for efficient processing.  As the "AT" will resonate at
odd integer multiples of the fundamental frequency, it is
necessary to specify the desired order of overtone when
ordering higher frequency crystals.

Drive Level

Drive level is the amount of power dissipated by the
crystal.  Drive level is usually specified in terms of micro
or milliwatts, with a typical value being 100 microwatts.

Quartz crystal units serve as the controlling element of
oscillator circuits by conversion of mechanical vibrations
to electrical current at a specific frequency.  This is
accomplished by means of the "Piezoelectric" effect.
Piezoelectricity is electricity created by pressure.  In a
piezoelectric material, the application of mechanical
pressure along an axis will result in the creation of an
electrical charge along an axis at right angles to the first.
In some materials, the obverse piezoelectric effect is found,
which means that the imposition of an electric field on
the ends of an axis will result in a mechanical deflection
along an axis at right angles to the first.  Quartz is uniquely
suited, in terms of mechanical, electrical and chemical
properties, for the manufacture of frequency control
devices.  Quartz crystal units which oscillate within certain
frequency and temperature ranges have been developed
over the years.  

Figure 1

 shows the location of specific

elements within a quartz stone.

The elements as shown above vibrate in various modes,
the most important of which are the extensional, flexural
and shear.  The mode of vibration determines the
maximum frequency, stability vs. temperature, and
resistance of a given element.  The various modes of
vibration are shown in

Series vs. Parallel

"Series" resonant crystals are intended for use in circuits
which contain no reactive components in the oscillator
feedback loop.   "Parallel" resonant crystals are intended
for use in circuits which contain reactive components
(usually capacitors) in the oscillator feedback loop.  Such
circuits depend on the combination of the reactive
components and the crystal to accomplish the phase shift
necessary to start and maintain oscillation at the specified
frequency.  Basic depictions of two such circuits are
shown below.

Figure 5

Load Capacitance

This refers to capacitance external to the crystal, contained
within the feedback loop of the oscillator circuit.  If the
application requires a "parallel" resonant crystal, the value
of load capacitance must be specified.    If the application
requires a "series" resonant crystal, load capacitance is
not a factor and need not be specified.  Load capacitance
is the amount of capacitance measured or computed
across the crystal terminals on the PCB.

Frequency Tolerance

Frequency tolerance refers to the allowable deviation from
nominal, in parts per million (PPM), at a specific
temperature, usually +25°C.

Frequency Stability

Frequency stability refers to the allowable deviation, in
parts per million (PPM), over a specified temperature
range.  Deviation is referenced to the measured frequency
at +25°C.

Aging

Aging refers to the cumulative change in frequency
experienced by a crystal unit over time.  Factors affecting
aging are excessive drive level, various thermal effects,
wire fatigue and frictional wear.  Circuit design
incorporating low operating ambients and minimum drive
level will reduce the aging rate.

Pullability

Pullability refers to the change in frequency of a crystal
unit, either from the natural resonant frequency (Fr) to a
load resonant frequency (F

L

), or from one load resonant

frequency to another. 

See Figure 6

.  The amount of

pullability exhibited by a given crystal unit at a given value
of load capacitance is a function of the shunt capacitance
(Co) and the motional capacitance (C

1

) of the crystal

unit.

Figure 6

Equivalent Circuit

The equivalent circuit, shown in 

Figure 7

, is an electrical

depiction of the quartz crystal unit when operating at a
frequency of natural resonance.  The Co, or shunt
capacitance, represents the capacitance of the crystal
electrodes plus the capacitance of the holder and leads.
R

, C

1

, and L

1

 compose the "motional arm" of the crystal

and are referred to as the motional parameters.  The
motional inductance (L

1

), represents the vibrating mass

of the crystal unit.  The motional capacitance (C

1

),

represents the elasticity of the quartz and the resistance
(R

1

), represents bulk losses occurring within the quartz.

Figure 7

Impedance/Reactance Curve

A crystal has two frequencies of zero phase, as illustrated
in 

Figure 8

.  The first, or lower of the two, is the Series

Resonant Frequency, denoted as 

(f

s).  At this point, the

crystal appears resistive in the circuit, impedance is at a
minimum and current flow is maximum.  As the frequency
is increased beyond the point of series resonance, the
crystal appears inductive in the circuit.  When the
reactances of the motional inductance and shunt
capacitance cancel, the crystal is at the Frequency of
Anti-resonance, denoted as 

(f

a).  At this point, impedance

is maximized and current flow is minimized.

Figure 8

Quality Factor (Q

)

The "Q" value of a crystal unit is a measure of the units
relative quality, or efficiency of oscillation.  The maximum
attainable stability of a crystal unit is dependent on the
"Q" value.  In 

Figure 8

 above, the separation between

the series and parallel frequencies is called the bandwidth.
The smaller the bandwidth, the higher the "Q" value, and
the steeper the slope of the reactance.  Changes in the
reactance of external circuit components have less effect
(less "pullability") on a high "Q" crystal, therefore such a
part is more stable.

Calculation of Load Capacitance

If the circuit configuration is as shown in Figure 5 for the
parallel version, the load capacitance may be calculated
by means of the following equation:

Cstray includes the pin to pin input and output capacitance
of the microprocessor chip at the 

Crystal 1

 and 

Crystal 2

pins, plus any parasitic capacitances.  As a rule of thumb,
Cstray may be assumed to equal 5.0 pF.  Therefore, if
C

L

1

 = C

L

2

 = 50pF, C

L

 = 30pF.

Trim Sensitivity

Trim sensitivity is a measure of the incremental fractional
frequency change for an incremental change in the value
of the load capacitance.  Trim sensitivity (S) is expressed
in terms of PPM/pF and is calculated by the following
equation:

Crystal controlled oscillators may be considered as consisting
of an amplifier and a feedback network that selects a part of
the amplifier output and returns it to the amplifier input. A
generalized depiction of such a circuit is shown below.

Figure 1.0

In order for an oscillator circuit to operate, two (2)
conditions must be met:

(A) The loop power gain must be equal to unity.
(B) The loop phase shift must be equal to 0, 2Pi, 4Pi, etc. radians.

The power fed back to the input of the amplifier must be
adequate to supply the oscillator output, the amplifier input,
and to overcome circuit losses.

The exact frequency at which an oscillator will operate is
dependent on the loop phase angle shifts within the oscillator
circuit.  Any net change in phase angle will result in a change
in the output frequency. As the usual goal of an oscillator is
to provide a frequency that is essentially independent of
variables, some means of minimizing the net phase shift must
be employed. Perhaps the best, and certainly the most
common means of minimizing the net phase shift is to use a
quartz crystal unit in the feedback loop.

The impedance of a quartz crystal changes so dramatically
with changes in the applied frequency that all other circuit
components can be considered as being of essentially
constant reactance. Therefore, when a crystal unit is used in
the feedback loop of an oscillator, the frequency of the crystal
unit will adjust itself so that the crystal unit presents a
reactance which satisfies the loop phase requirements.
A depiction of the reactance vs. frequency of a quartz crystal
unit is shown below.

Figure 2.0

As is apparent from Figure 2.0, a quartz crystal unit has two
frequencies of zero phase.  The first, or lower of the two, is
the series resonant frequency, usually abbreviated as Fs.  The
second, or higher of the two frequencies of zero phase is the
parallel, or anti-resonant frequency, usually abbreviated as
Fa.  Both the series and parallel resonant frequencies appear
resistive in an oscillator circuit. At the series resonant point,
the resistance is minimal and the current flow is maximal.

At the parallel point, the resistance is maximal and the current
flow is minimal. Therefore, the parallel resonant frequency,
Fa, should never be used as the controlling frequency of an
oscillator circuit.

A quartz crystal unit can be made to oscillate at any point
along the line between the series and parallel resonant points
by the inclusion of reactive components (usually capacitors)
in the feedback loop of the oscillator circuit. In such a case,
the frequency of oscillation will be higher than the series
resonant frequency but lower than the parallel resonant
frequency. Because of the fact that the frequency resulting
from the addition of capacitance is higher than the series
resonant frequency, it is usually called the parallel frequency,
though it is lower than the true parallel frequency.

Just as there are two frequencies of zero phase associated
with a quartz crystal unit, there are two primary  oscillator
circuits. These circuits are generally described by the type
of crystal unit to be used, namely “series” or “parallel.”

SERIES CIRCUIT:

A series resonant oscillator circuit uses a crystal which is
designed to operate at its natural series resonant frequency.
In such a circuit, there will be no capacitors in the feedback
loop. Series resonant oscillator circuits are used primarily
because of their minimal component count. These circuits
may, however,  provide feedback paths other than through the
crystal unit. Therefore,  in the event of crystal failure, such a
circuit may continue to oscillate at some arbitrary frequency.
A depiction of a basic series resonant oscillator circuit is
given below.

Figure 3.0

As is apparent from Figure 3.0, a series resonant oscillator
circuit provides no means of adjusting the output frequency,
should adjustment be required.  In the above circuit, resistor
R1 is used to bias the inverter and to cause it to operate in its
linear region. This resistor also provides negative feedback
to the inverter.  

Capacitor C1

 is a coupling capacitor, used

to block DC voltage.  

Resistor R2

 is used to bias the crystal

unit. This resistor strongly influences the drive current seen
by the crystal unit, therefore care must be taken that too small
a value is not chosen.  

Crystal unit Y1

 is a series resonant

crystal unit, specified to operate at the desired frequency
and with the desired frequency tolerance and stability.

PARALLEL CIRCUIT:

A parallel resonant oscillator circuit uses a crystal unit which
is designed to operate with a specified value of load
capacitance. This will result in a crystal frequency which is
higher than the series resonant frequency but lower than the
true parallel resonant frequency. These circuits do not provide
paths other than through the crystal unit to complete the
feedback loop. In the event of crystal unit failure, the circuit
will not continue to oscillate.  A basic depiction of a parallel
resonant circuit is given below.

Figure 4.0

This circuit uses a single inverter, with two capacitors in the
feedback loop. These capacitors comprise the “load
capacitance” and together with the crystal unit, establish the
frequency at which the oscillator will operate. As the value
of the load capacitance is changed, so is the output frequency
of the oscillator. Therefore, this circuit does provide a
convenient means of adjusting the output frequency, should
adjustment be required.
The resistors R

1

 and R

2

 serve the same functions as detailed

for the series resonant circuit shown in Figure 3.0. The two
load capacitors, C

L1

 and C

L2

, serve to establish the frequency

at which the crystal unit and therefore the oscillator will
operate. Crystal unit Y

1

 is a parallel resonant crystal unit,

specified to operate with a specified value of load
capacitance, at the desired frequency and with the desired
frequency tolerance and stability.

LOAD CAPACITANCE:

Reference has been made to a “specified value of load
capacitance.” Load capacitance may be defined as “that value
of capacitance, either measured or calculated, present in the
oscillator circuit, across the connection points of the crystal.”
In the case of a series resonant circuit, there is no capacitance
present between the connecting points of the crystal unit and
therefore, load capacitance need not be specified for a series
resonant crystal unit. In the case of a parallel resonant
oscillator circuit, capacitance is present. As a direct
measurement of this capacitance is impractical, it is usually
necessary to calculate the value. The calculation of the value
of the load capacitance is done with the following equation:

 C

L

 =                   + C

S 

                 (1)

Where C

L1

 and C

L2 

are the load capacitors and C

S

 is the

circuit stray capacitance, usually 3.0 to 5.0 pF.

It must be noted that changes in the value of the load
capacitance will result in changes in the output frequency of
the oscillator. Therefore, if precise frequency control is
required, then a precise specification of load capacitance is
required. To illustrate, assume that a crystal unit is specified
to operate at a frequency of 20.000 MHz with a load
capacitance of 20.0 pF. Assume that the crystal unit is then
placed in a circuit which presents a value of 30.0 pF. The
frequency of the crystal unit will then be lower than the
specified value. Conversely, should the circuit in question
present a value of 10.0 pF, the frequency will be higher than
the specified value. The relationship between frequency and
load capacitance is shown below.

Figure 5.0

DRIVE LEVEL:

The “drive level” is the power dissipated by the crystal unit
while operating. The power is a function of the applied
current, and is usually expressed in terms of Milliwatts or
Microwatts. Crystal units are specified as having certain
maximum values of drive level, which change as functions of
the frequency and mode of operation. It is well to consult
with the crystal unit vendor as to the maximum value of drive
level allowed for a particular crystal unit. Exceeding the
maximum drive level for a given crystal unit may result in
unstable operation, increased aging rates, and in some cases,
catastrophic damage. The drive level may be calculated by
the following equation:

POWER = (I

rms

2 

* R)

 (2)

Where 

I

 is the 

rms

 current through the crystal unit and R is

the maximum resistance value of the specific crystal unit in
question. Equation (2) is simply “Ohms law” for power.

Measurement of the actual drive level in an operating
oscillator circuit may be accomplished by temporarily
inserting a resistor in series with the crystal unit. The resistor
must be of the same ohmic value as the crystal unit. The
voltage drop across the resistor may then be read and the
current and power dissipation calculated. The resistor must
then be removed. As an alternative means of measuring the
drive level, a current probe may be used at the output lead of
the crystal unit, if space permits.

FREQUENCY VS OVERTONE MODE:

The frequency of a quartz crystal unit is limited by the physical
dimensions of the vibrating quartz element. In some cases,
the limiting dimension(s) are the length and width. In the case
of the most popular crystal unit, the “AT” cut crystal unit, the
limiting dimension is the thickness of the vibrating quartz
element. As the thickness is diminished, the frequency is
increased. At some point, usually around 30.000 MHz, the
thickness of the quartz plate becomes too thin for processing.

Should it be desired to develop an oscillator at a frequency
higher than the limiting frequency, advantage must be taken
of the fact that quartz crystal units will oscillate at odd integer
multiples of their “fundamental” frequency. We may define
the “fundamental” frequency as “that frequency which
naturally occurs at a given set of mechanical dimensions.”
Therefore, if a crystal unit has a fundamental frequency of
10.0 MHz, it can also be made to oscillate at 3, 5, 7, etc.
times the fundamental. That is, the unit will oscillate at 30.0,
50.0, 70.0, etc. MHz. These multiples of the fundamental
frequency are called “overtones” and are identified by the
integer of multiplication, as in the “third overtone”, the “fifth
overtone”, etc. When use at an overtone frequency is
required, the crystal unit must be specified to operate at the
desired frequency and on the desired overtone. One should
never attempt to order a fundamental mode crystal unit and
then operate it at an overtone frequency. This is so due to the
fact that the crystal manufacturing processes differ for
fundamental and overtone crystal units.

In many cases, the characteristics of the integrated circuit
used in a particular oscillator design dictate that the
fundamental frequency of the crystal unit be suppressed in
order to ensure operation at the desired frequency and on
the desired overtone. In such cases, it is usually necessary to
modify the oscillator circuit. One method of modification
is to add a “tank” circuit, consisting of an inductor and a
capacitor.  These modifications are shown in 

Figure 6.0

 and

7.0

Figure 6.0

Figure 6.0 

depicts the modification of a series resonant

circuit while 

Figure 7.0

 depicts the modification of a parallel

resonant circuit.

Figure 7.0

In both cases, the tank circuit is tuned to resonate at some
frequency between the fundamental and the desired
frequency. This results in the unwanted frequency being
shunted to ground, leaving only the desired frequency being
present at the output of the oscillator.

DESIGN CONSIDERATIONS:

For good operation of an oscillator circuit, certain design
considerations should be followed. In all cases, it is
recommended that parallel traces be avoided in order to
reduce circuit stray capacitance. All traces should be kept as
short as possible and components should be isolated in order
to prevent coupling. Ground planes should be used to isolate
signals.

NEGATIVE RESISTANCE:

For optimum performance, an oscillator circuit must be
designed in such a way as to enhance “negative resistance,”
which is sometimes called the “oscillation allowance.”
Evaluation of the amount of negative resistance in a given
circuit is accomplished by temporarily installing a variable
resistor in series with the crystal unit. The resistor should be
set initially at its lowest setting, preferably close to zero
ohms. The oscillator is then started and the output monitored
on an oscilloscope. The variable resistor is then adjusted so
that resistance is increased while the output is continuously
monitored. At some value of resistance, oscillation will be
stopped. At this point, the variable resistor is measured to
determine the ohmic value at which oscillation ceased. To
this value, the maximum resistance of the crystal unit, as
specified by the vendor, must be added. The total ohmic
resistance is deemed to be the “negative resistance” or the
“oscillation allowance.” For good, reliable circuit operation,
it is recommended that the negative resistance be a minimum
of five times the specified maximum resistance value of the
crystal unit.

Values of negative resistance exceeding five times the maxi-
mum resistance of the crystal unit are better yet. As negative
resistance tends to decrease at elevated temperatures, it is
recommended that the test be performed at the highest tem-
perature of the operating range.

FREQUENTLY ASKED QUESTIONS

TECHNICAL INFO

What is the difference between series resonant and parallel
resonant crystals?

All quartz crystal resonators have a series resonant
frequency (f

s

, frequency of lowest impedance). At this

frequency, the crystal appears resistive in the circuit.
Crystals can be “pulled” from this series frequency by
adding reactance (capacitance) in series with the crystal.
When operated in combination with an external load
capacitance (C

L

) the crystal oscillates in a frequency range

slightly above its series resonant frequency. This is the
parallel (load resonant) frequency.

When ordering a parallel crystal, always specify the
nominal parallel resonant frequency and the amount of load
capacitance in picofarads (pF). Alternatively, a standard
value of C

L

 (such as 20pF) can be ordered; the capacitor

values are then calculated to match the crystal C

L

. Note

that a series type will oscillate in a parallel oscillator, and
vice versa. The observable difference is a frequency offset
of less than + 1000 PPM (0.1%) from the nominal
frequency.

The load capacitance (C

L

) of my parallel resonant

crystal is rated at 20pF. How do I calculate the value of
the load capacitors used in my parallel resonant
oscillator circuit?

Use this formula to approximate the value of capacitors
needed:

C

L

=((C

1

 x C

2

) / (C

1

 + C

2

)) + C

stray

C

stray

 is the stray capacitance in the circuit, typically 2-

5pF. If the oscillation frequency is high, the capacitor
values should be increased to lower the frequency. If the
frequency is low, the capacitor values should be decreased,
thus raising the oscillation frequency. It is desirable to
keep C

1

 and C

2

 of equal value for optimum symmetry.

When C

L

=20pF, C

1

 and C

2

 will be approximately 27-33pF

each, depending on the amount of stray capacitance.

Can I get crystals rated for –40° C to +85° C?

Yes, this industrial temperature range (–40° C to +85° C)
is optional on most crystals. Depending on the crystal
package, temperature ranges of up to -55° C to +105° C
may be available. Contact Fox’s engineering department
to discuss your specific requirements.

What happens if I operate a crystal outside of its specified
temp range?

We do not recommend that you operate a crystal outside
of its specified temp range. The most notable change will
be a greater frequency drift due to the increased
temperature extremes. Another and more serious problem
that can occur is activity dips. Activity dips can cause the
oscillator to stop oscillating at a specific temperature.

What happens if I operate a crystal over its maximum
drive level spec?

Exceeding the maximum drive level (power dissipation)
of a crystal can lead to an increased rate of aging, Drive
Level Dependency (DLD) problems, increased intensity
of activity dips that can stop oscillation and, at very high
drive levels, breakage of the crystal blank.

What is an activity dip?

An activity dip is defined as an abrupt increase in Effective
Series Resistance (ESR) with an associated shift in
resonant frequency over a narrow range of a few degrees
Celsius. Activity dips can cause an oscillator to stop
oscillating at a specific temperature, then restart as the
temperature continues to change. This is because the
oscillator has insufficient loop gain to maintain
oscillation. The amount and intensity of activity dips are
proportional to the drive level. As the drive level increases,
so does the intensity of the activity dips.

I have an existing design that uses a HC49U. What
should I consider if I change to the smaller HC49S
crystal, or an SMD crystal?

Drive Level – HC49U crystals are typically rated 1.0mW
max, while the HC49S and most SMD crystals are rated at
only 0.5mW or 0.1mW maximum. See question 5 for more
information on exceeding the maximum drive level of a
crystal.
Pullability – some applications require tuning the
frequency of the oscillator, either by mechanically or
electrically changing the value of load capacitance. The
HC49S and surface mount crystals have less pullability
than the HC49U. It is important to verify whether the
HC49S or the surface mount crystal will have sufficient
pull range for the application.
ESR – The Equivalent Series Resistance (ESR) is generally
higher with the HC49S and surface mount crystals, and
can cause a problem if the oscillator circuit does not have
sufficient loop gain.

Why is there more than one holder designator for the
same package?

There are three ways to seal a crystal package: solder seal,
cold weld and resistance weld. Most manufacturers use
the resistance weld method because it is superior to the
other two methods. Since not all customer prints have been
changed to include the resistance weld crystals, a cross
reference is provided below.

What information is necessary to order a crystal?

The minimum information needed is the Holder or
Package, Frequency, and Correlation (series resonant, or
load capacitance if parallel resonant). All other
specifications will be per our standard specifications for
the indicated holder. All specifications that differ from
our standard specifications must also be supplied when
ordered.

Should I focus my design on a series or parallel crystal?

For most applications, the parallel crystal is a good choice,
in that the parallel design is more widely standardized and
is more likely to be a stock item for future purchases.

Why don’t HC49S and surface mount crystals pull as
much as HC49U crystals?

The HC49U crystal utilizes a circular AT-cut crystal blank.
Due to their small size, most surface mount crystals use a
rectangular AT-strip cut crystal blank. (“Strip” refers to
the rectangular shape of the blank.) While both are AT-cut
blanks, several differences exist due to their different
geometries. In general, given the same frequency and
overtone, an AT-strip cut will have a lower Shunt
Capacitance (C

O

) and Motional Capacitance (C

1

) than the

AT-cut. Because pullability is a function of the capacitance
ratio C

O

/C

1

, AT-strip crystals have less pullability.

What is the difference between AT- and BT-cuts?

Both AT and BT indicate singularly rotated “Y”-axis cuts
through the quartz crystal. The BT is cut at an angle
approximately opposite that of the AT.

BT-cut blanks are thicker than AT-cuts at the same
frequency; therefore, higher fundamental mode
frequencies are possible with the BT before the blank
becomes too thin to process. BT-cuts have a parabolic
frequency vs. temperature response while AT-cuts have a
cubic response. Thus, over a given temperature range, the
BT will exhibit a greater frequency shift than the AT. In
addition, BT-cuts tend to have a lower capacitance ratio
(C

O

/C

1

) and, as a result, less pullability.

What are the differences between AT-cuts and AT-strip
cuts?

The differences are in size, shape and some performance
characteristics. AT-cut crystal blanks are circular, and AT-
strip cut crystal blanks are rectangular. Both types are AT-
cuts, but several differences in performance
characteristics exist because of the different geometries
of the blanks. In general, given the same frequency and
overtone, the AT-strip will have a lower value of Shunt
Capacitance (C

O

) and Motional Capacitance (C

1

). It will

also have a higher value of Effective Series Resistance
(ESR) and Motional Inductance (L

1

). Because pullability

is a function of C

O

 and C

1

, AT-strip cut crystals have less

pullability than circular AT-cut crystals.
