描述 Description

The 843251I-04 is a 10Gb/12Gb Ethernet Clock Generator and a member of the family of high performance devices from IDT. The 843251I-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 843251I-04 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.
