General Description

The ICS843252-04 is a 10Gb/12Gb Ethernet Clock Generator. The

ICS843252-04 can synthesize 10 Gigabit Ethernet and 12 Gigabit

Ethernet with a 25MHz crystal. It can also generate SATA and 10Gb

Fibre Channel reference clock frequencies with the appropriate

choice of crystals. The ICS843252-04 has excellent phase jitter

performance and is packaged in a small 16-pin TSSOP, making it

ideal for use in systems with limited board space.
