General Description

The 840051I is a Gigabit Ethernet Clock Generator and a member of the HiPerClocksTM family of high performance devices from ICS.

The 840051I can synthesize 10 Gigabit Ethernet, SONET, or Serial ATA reference clock fre-quencies with the appropriate choice of crystal and output divider.

The 840051I 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.
