ESCRIPTION
The ICS840051 is a Gigabit Ethernet Clock
Generator and a member of the HiPerClocks
TM
family of high performance devices from ICS.
The ICS840051 can synthesize 10 Gigabit
Ethernet, SONET, or Serial ATA reference clock
frequencies with the appropriate choice of crystal and
output divider. The ICS840051 has excellent phase jitter
performance and is packaged in a small 8-pin TSSOP,
making it ideal for use in systems with limited board space.
