DATASHEET

MULTIPLIER AND ZERO DELAY BUFFER

Description

The ICS570 is a high-performance Zero Delay Buffer (ZDB)

which integrates IDT’s proprietary analog/digital Phase

Locked Loop (PLL) techniques. The A version is

recommended for 5 V designs and the B version for

3.3 V designs. The chip is part of IDT’s ClockBlocks

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. There are two outputs on the chip, one being a

low-skew divide by two of the other output. The device

incorporates an all-chip power down/tri-state mode that

stops the internal PLL and puts both outputs into a high

impedance state.

The ICS570 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.

The ICS570 A and B versions were designed to improve

input to output jitter from the original ICS570M version, and

are recommended for all new designs.
