General Description

The ICS843002I is a 2 output LVPECL synthesizer optimized to generate Fibre Channel reference HiPerClockS™ clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.

Using a 26.5625MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz, 159.375MHz, 106.25MHz, and 53.125MHz.

The ICS843002I uses ICS’ FemtoClockTM low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements.

Key Features

  • Two 3.3V or 2.5V LVPECL outputs.
