ESCRIPTION
The ICS842031I-01 is an Ethernet Clock
Generator and a member of the HiPerClocks
TM
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.
