General Description

The PS2500 Direct Digital Modulation Fractional-N frequency synthesizer provides ultra-fine frequency resolution, fast switching speed, and low phase-noise performance.

This synthesizer is a key building block in designing high-performance narrowband and multi-band radio systems that require low power and fine step size.

The ultra-fine step size of less than 100 Hz allows this synthesizer to be used in very narrowband wireless applications.

Key Features

  • 2.2 GHz maximum operating frequency.
  • 500 MHz maximum auxiliary synthesizer.
  • Ultra-small step size 100 Hz or less.
  • High-reference frequency enables larger loop bandwidth PLL.
  • Fast switching speed.
  • Phase-noise to -92 dBc/Hz inside the loop filter bandwidth.
  • Spurious -70 dBc/Hz inside the loop filter bandwidth.
  • Software programmable power-down modes.
  • High-speed serial interface.
  • 3-wire programming.
  • P.
