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.
