General Description

The ICS840004-01 is a 4 output LVCMOS/LVTTL 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_SEL1:0): 156.25MHz, 125MHz, and 62.5MHz.

The ICS840004-01 uses ICS’ 3rd generation low phase noise VCO technology and can www.DataSheet4U.com achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements.
