General Description

UMA1015AM The UMA1015AM is a low-power dual frequency synthesizer for radio munications which operates in the 50 to 1100 MHz frequency range.

Each synthesizer consists of a fully programmable main divider, a phase and frequency detector and a charge pump.

There is a fully programmable reference divider mon to both synthesizers which operates up to 35 MHz.

Key Features

  • Two fully programmable RF dividers up to 1.1 GHz.
  • Fully programmable reference divider up to 35 MHz.
  • 2 : 1 or 1 : 1 ratio of selectable reference frequencies.
  • Fast three-line serial bus interface.
  • Adjustable phase comparator gain.
  • Programmable out-of-lock indication for both loops.
  • On-chip voltage doubler.
  • Low current consumption from 3 V supply.
  • Separate power-down mode for each synthesizer.
  • Up to 4 open-.
