GENERAL DESCRIPTION

The

84427

is

a

Cr ystal-to-LVDS

F requency

Synthesizer/Fanout Buffer. The output frequency can be

programmed using the frequency select pins. The low phase

noise characteristics of the 84427 make it an ideal clock source

for 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, OC3 and

OC12 applications.
