family of high performance devices from ICS. The
ICS843031 can synthesize 1 Gigabit Ethernet,
SONET, or Serial ATA reference clock frequencies
with the appropriate choice of crystal and output divider. The
ICS843031 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.
