MULTIPLIER AND ZERO DELAY BUFFER
DATASHEET
ICS2402
Description
The ICS2402 is a high-performance Zero Delay Buffer
(ZDB) which integrates IDT’s proprietary analog/digital
Phase-Locked Loop (PLL) techniques. The chip is part
of IDT’s ClockBlocksTM family and was designed as a
performance upgrade to meet today’s higher speed and
lower voltage requirements. The zero delay feature
means that the rising edge of the input clock aligns with
the rising edges of both output clocks, giving the
appearance of no delay through the device.
The ICS2402 is ideal for synchronizing outputs in a
large variety of systems, from personal computers to
data communications to graphics/video. By allowing
off-chip feedback paths, the device can eliminate the
delay through other devices.
