General Description
The UMA1020AM 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 nominal 5 V supplies.
Key Features
- Low current from 3 V supply.
- Fully programmable RF divider.
- 3-line serial interface bus.
- Second synthesizer to control first IF or offset loop frequency.
- Independent fully programmable reference dividers for each loop, driven from external crystal oscillator.
- Dual phase detector outputs to allow fast frequency switching.
- Dual power-down modes.
