UMA1022M - Low cost dual frequency synthesizer for radio telephones

Description

The UMA1022M BICMOS device integrates prescalers, programmable dividers, a crystal oscillator/buffer and phase comparators to implement two phase-locked loops.

The device is designed to operate from 3 NiCd or a single LiIon cell in pocket phones, or from an external 3 V supply.

Features

  • Low phase noise.
  • Low current from 3 V supply.
  • Fully programmable dividers.
  • 3-line serial interface bus.
  • Input reference buffer configurable as an oscillator with external crystal resonator.
  • Wide compliance voltage charge pump outputs.
  • Two power-down input control pins.
