General Description

The ICS843002-01 is a 2 output LVPECL synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.

Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz.

The ICS843002-01 uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements.

Key Features

  • Two 3.3V LVPECL outputs.
  • Selectable crystal oscillator interface or LVCMOS single-ended input.
  • Supports the following input frequencies: 156.25MHz, 125MHz and 62.5MHz.
  • VCO range: 560MHz - 680MHz.
  • RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz-20MHz): 0.54ps (typical).
  • Typical phase noise at 156.25MHz Phase noise: Offset Noise Power 100Hz -97.3 dBc/Hz 1KHz -119.1 dBc/Hz 10KHz -126.4 dBc/Hz 100KHz -127.6 dBc/Hz.
  • Ful.
