描述
The 843051I is a Gigabit Ethernet clock generator and a member of the HiPerClocks™ family of high-performance devices. The 843051I can synthesize 10 Gigabit Ethernet, SONET, or Serial ATA reference clock frequencies with the appropriate choice of crystal and output divider. The 843051I 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.
