The ICS842031I-01 is an Ethernet Clock Generator and a member of the HiPerClocksTM HiPerClockSTM family of high performance devices from ICS. The ICS842031I-01 uses an 18pF parallel resonant crystal over the range of 19.6MHz - 27.2MHz. For Ethernet applications, a 25MHz crystal is used to generate 312.5MHz. The ICS842031I-01 has excellent <1ps phase jitter performance, over the 1.875MHz - 20MHz integration range. The ICS842031I-01 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
