SI5327 - ANY-FREQUENCY PRECISION CLOCK MULTIPLIER/JITTER ATTENUATOR

Description

The Si5327 is a jitter-attenuating precision clock multiplier for applications requiring sub 1 ps jitter performance.

The Si5327 accepts two input clocks ranging from 2 kHz to 710 MHz and generates two output clocks ranging from 2 kHz to 808 MHz.

Features

  • Generates any frequency from 2 kHz.
  • Dual clock inputs with manually to 808 MHz from an input frequency controlled hitless switching of 2 kHz to 710 MHz.
  • Free run and VCO freeze modes.
  • Ultra-low jitter clock outputs with jitter.
  • Support for ITU G.709 and custom generation as low as 0.5 ps rms FEC ratios (255/238, 255/237, (12 kHz.
  • 20 MHz) 255/236).
  • Integrated loop filter with selectable.
  • LOL and LOS alarm outputs loop bandwidth (4 to 525 Hz).
