ESCRIPTION
The ICS842023I is an Ethernet Clock
Generator and a member of the HiPerClocks
TM
family of high performance devices from ICS.
For Ethernet applications, a 25MHz crystal is
used to generate 250MHz. The ICS842023I
uses ICS’ 3rd generation low phase noise VCO tech-
nology and can achieve <1ps rms phase jitter, easily
meeting Ethernet jitter requirements. The ICS842023I
is packaged in a small 8-pin TSSOP, making it ideal
for use in systems with limited board space.
