ESCRIPTION
The ICS843023 is a Gigabit Ethernet Clock
Generator and a member of the HiPerClocks
TM
family of high performance devices from ICS. The
ICS843023 uses a 25MHz crystal to synthesize
250MHz. The ICS843023 has excellent phase jitter
performance, over the 1.875MHz – 20MHz integration range.
The ICS843023 is packaged in a small 8-pin TSSOP, making it
ideal for use in systems with limited board space.
