GENERAL DESCRIPTION
The ICS843031 is a 1 Gigabit Ethernet Clock Generator. 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.
