Low-voltage dual frequency synthesizer for radio telephones

GENERAL DESCRIPTION\nThe OM5156M BICMOS device integrates prescalers, programmable dividers, and phase comparators to implement two phase-locked loops. The device is designed to operate from 3 NiCd cells, in pocket phones, with low current and a wide supply voltage range from 2.7 to 5.5 V.\nThe prin • Low current from 3 V supply\n• Fully programmable RF divider\n• 3-line serial interface bus\n• Second synthesizer to control first IF or offset loop frequency\n• Independent fully programmable reference dividers for each loop, driven from external crystal oscillator\n• Dual phase detector outputs ;
