General Description

The ICS840004-11 is a 4 output LVCMOS/ LVTTL Synthesizer optimized to generate HiPerClockS™ 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, 125MHz and 62.5MHz can be generated based on one frequency select pin (F_SEL).

The ICS840004-11 uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower www.DataSheet4U.com typical random rms phase jitter, easily meeting Ethernet jitter requirements.

Key Features
