ICS671-03

REV D 051310

Description

The ICS671-03 is a low phase noise, high speed PLL

based, 8 output, low skew zero delay buffer. Based on IDT’s

proprietary low jitter Phase Locked Loop (PLL) techniques,

the device provides eight low skew outputs at speeds up to

133 MHz at 3.3 V. The outputs can be generated from the

PLL (for zero delay), or directly from the input (for testing),

and can be set to tri-state mode or to stop at a low level. For

normal operation as a zero delay buffer, any output clock is

tied to the FBIN pin.
