Description
Motorola 45106P IC CMOS PLL frequency synthesizer 4.5-12V 5.12mHz DIP
T he MC145106 is a phaselocked loop (PLL) frequency synthesizer constructed in CMOS on a single monolithic structure. This synthesizer finds applications in such areas as CB and FM transceivers. The device contains an oscillator/amplifier, a 210 or 211 divider chain for the oscillator signal, a programmable divider chain for the input signal, and a phase detector. The MC145106 has circuitry for a 10.24 MHz oscillator or may operate with an external signal. The circuit provides a 5.12 MHz output signal, which can be used for frequency tripling. A 29 programmable divider divides the input signal frequency for channel selection. The inputs to the programmable divider are standard groundtosupply binary signals. Pulldown resistors on these inputs normally set these inputs to ground enabling these programmable inputs to be controlled from a mechanical switch or electronic circuitry. The phase detector may control a VCO and yields a high level signal when input frequency is low, and a low level signal when input frequency is high. An outoflock signal is provided from the onchip lock detector with a “0” level for the outoflock condition. · · · · · · · · · · · Single Power Supply Wide Supply Range: 4.5 to 12 V Provision for 10.24 MHz Crystal Oscillator 5.12 MHz Output Programmable Division Binary Input Selects up to 29 OnChip PullDown Resistors on Programmable Divider Inputs Selectable Reference Divider, 210 or 211 (Including ÷ 2) ThreeState Phase Detector See Application Note AN535 and Article Reprint AR254 Chip Complexity: 880 FETs or 220 Equivalent Gates See the MC1451512 and MC1451522 for Higher Performance and Added Flexibility
