NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the
           device. These ratings are stress specifications only. Functional operation of product at these conditions or any

           maximum rating conditions for extended periods may affect product reliability.

The ICS840004I-01 is a 4 output LVCMOS/LVTTL 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_SEL1:0): 156.25MHz, 125MHz, and 62.5MHz. The ICS840004I-01 uses ICS'3^rd generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements. The ICS840004I-01 is packaged in a small 20-pin TSSOP package.
