Overview
Description
The 843031 is a 1 Gigabit Ethernet clock generator. The 843031 can synthesize 1 Gigabit Ethernet, SONET, or Serial ATA reference clock frequencies with the appropriate choice of crystal and output divider. The 843031 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.
