Description

The ICS843002-01 is a 2 output LVPECL synthesizer optimized to generate Ethernet 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 ICS843002-01 uses ICS'3^rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The ICS843002-01 is packaged in a small 20-pin TSSOP package.
