DESCRIPTION:
• Phase-Lock Loop Clock Distribution for Applications ranging
from 10MHz to 200MHz 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
