ESCRIPTION
The ICS840001I is a Fibre Channel Clock
Generator and a member of the HiPerClocks
TM
family of high performance devices from ICS. The
ICS840001I uses a 26.5625MHz crystal to
synthesize either 106.25MHz or 212.5MHz, using
the FREQ_SEL pin. The ICS840001I has excellent phase jitter
performance, over the 637kHz – 5MHz integration range. The
ICS840001I is packaged in a small 8-pin TSSOP, making it
ideal for use in systems with limited board space.
