GENERAL DESCRIPTION

The 840051 is a Gigabit Ethernet Clock Generator and a

member of the family of high performance devices from IDT.

The 840051 can synthesize 10 Gigabit Ethernet,

SONET, or Serial ATA reference clock frequencies

with the appropriate choice of crystal and

output divider. The 840051 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
