GENERAL DESCRIPTION

The 844008I-46 is a 10Gb Ethernet Clock Generator and a member

of the HiPerClocks™ family of high performance devices from

IDT. The 844008I-46 can synthesize 156.25MHz or 100MHz with

a 25MHz crystal. It has a total of 8 LVDS outputs. The 844008I-46

has excellent phase jitter performance and is packaged in a 32

Lead VFQFN package, making it ideal for use in systems with

limited board space.
