FEATURES:

DESCRIPTION:

• Phase-Lock Loop Clock Distribution for Applications ranging

from 10MHz to 133MHz operating frequency

• Distributes one clock input to two banks of four outputs

• Separate output enable for each output bank

• External feedback (FBK) pin is used to synchronize the outputs

to the clock input
