Description
The is a monolithic low power, high performance dual frequency synthesizer fabricated in QUBiC BiCMOS technology. Featuring Fractional-N division with selectable modulo or 8 implemented in the Main synthesizer to allow the phase detector comparison frequency to be five or eight times the channel spacing. This feature reduces the overall division ratio yielding a lower noise floor and faster channel switching. The phase detectors and charge pumps are designed to achieve phase detector comparison frequencies 5MHz. A triple modulus prescaler (divide 64/65/72) is integrated on chip with a maximum input frequency of 1.04GHz. Programming and channel selection are realized by a high speed 3-wire serial interface.
