FREQUENCY SYNTHESIZERS
MC145104, MC145107, MC145109, MC145112 phase locked loop (PLL) frequency synthesizer parts constructed with CMOS devices single monolithic structure. These synthesizers find applications such areas transceivers. device contains oscillator/amplifier, divider chain oscillator signal, programmable divider chain input signal phase detector. MC145104/5112 have circuitry 10.24 oscillator operate with external signal. MC145107/5109 require external reference signal. Several circuits provide 5.12 output signal, which used frequency tripling. (MC145109/5112) (MC145104/5107) programmable divider divides input signal frequency channel selection. inputs programmable divider standard ground-to-supply binary signals. Pulldown resistors these inputs normally these inputs ground enabling these programmable inputs controlled from mechanical switch electronic circuitry.
phase detector control yields high level signal when input frequency low, level signal when input frequency high. lock signal provided from on-chip lock detector with level lock condition.
