ICS574

Zero Delay, Low Skew Buffer

Description

The ICS574 is a low jitter, low-skew, high performance

PLL-based zero delay buffer for high speed

applications. Based on ICS’s proprietary low jitter

Phase Locked Loop (PLL) techniques, the device

provides four low skew outputs at speeds up to 160

MHz at 3.3 V. When one of the outputs is connected

directly to FBIN, the rising edge of each output is

aligned with the rising edge of the input clock. External

delay elements connected in the feedback loops will

cause the outputs to occur before the inputs by the

amount of propagation delay of the external element.

ICS manufactures the largest variety of clock

generators and buffers, and is the largest clock

supplier in the world.
