General Description

The ICS843002I-01 is a 2 output LVPECL synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequencies and is a member of the HiPerClocks TM 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 ICS843002I-01 uses ICS’ FemtoClock TM 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 or 2.5V LVPECL outputs.
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input.
  • Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz.
  • VCO range: 560MHz - 680MHz.
  • RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz-20MHz): 0.55ps (typical).
  • Output skew: 30ps (maximum).
  • Supply Voltage Modes Core/Outputs 3.3/3.3 2.5/2.5.
  • -40°C to 85°C ambient operating temperature.
