SA7016 - 1.3GHz low voltage fractional-N synthesizer

Description

The SA7016 BICMOS device integrates programmable dividers, charge pumps and a phase comparator to implement a phase-locked loop.

The device is designed to operate from 3 NiCd cells, in pocket phones, with low current and nominal 3 V supplies.

Features

  • Low phase noise.
  • Low power.
  • Fully programmable main divider.
  • Internal fractional spurious compensation.
  • Hardware and software power down.
  • Split supply for VDD and VDDCP QUICK.
