UMA1016AT - Frequency synthesizer for radio communication equipment

General Description

The UMA1016xT is a low power synthesizer for radio communications.

Manufactured in bipolar technology, it is designed for a 70 to 1000 kHz channel spacing in the 500 to 1000 MHz band.

The channel is programmed via a 3-wire serial bus.

Key Features

  • RF input frequencies to 1 GHz.
  • Fully programmable RF divider.
  • 3-wire serial bus interface.
  • On-chip 3 to 16 MHz crystal oscillator.
  • Mask programmable ÷2 to ÷31 reference divider ratio.
  • Up to 1 MHz channel spacing.
  • Crystal frequency buffered output.
  • Dual register architecture for fast Tx/Rx switching in TDD single synthesizer systems.
  • Phase detector compensated for supply and temperature variations.
  • Power-do.
