ICS840021
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS840021 is a Gigabit Ethernet Clock
Generator and a member of the HiPerClocksTM
family of high performance devices from ICS. The
ICS840021 uses a 25MHz crystal to synthesize
125MHz.The ICS840021 has excellent phase jitter
performance, over the 1.875MHz – 20MHz integration range.
The ICS840021 is packaged in a small 8-pin TSSOP, making it
ideal for use in systems with limited board space.
