General Description

The ICS840004I is a 4 output LVCMOS/LVTTL Synthesizer optimized to generate Fibre Channel HiPerClockS™ reference 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_SEL1:0): 212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and 53.125MHz.

The ICS840004I uses ICS’ 3rd generation low phase www.DataSheet4U.com noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Fibre Channel jitter requirements.

Key Features
