General Description

GENERAL DESCRIPTION UMA1005T The UMA1005T is a low-power, high-performance dual frequency synthesizer fabricated in CMOS technology.

Fractional-N division with selectable modulo 5 or 8 is implemented in the main synthesizer.

The detectors and charge pumps are designated to achieve 10 to 5000 kHz channel spacing using fractional-N decreases the channel spacing by a factor 5 or 8.

Key Features

  • Fast locking by ‘Fractional-N’ divider.
  • Auxiliary synthesizer.
  • Digital phase comparator with proportional and integral charge pump output.
  • High-speed serial input.
  • Low-power consumption.
  • Programmable charge pump currents.
  • Supply voltage range 2.9 to 5.5 V.
