DATASHEET
LOW PHASE NOISE ZERO DELAY BUFFER
ICS571
IDT / ICS LOW PHASE NOISE ZERO DELAY BUFFER
1
ICS571
REV H 051310
Description
The ICS571 is a high speed, high output drive, low phase
noise Zero Delay Buffer (ZDB) which integrates IDT’s
proprietary analog/digital Phase Locked Loop (PLL)
techniques. IDT introduced the world standard for these
devices in 1992 with the debut of the AV9170, and updated
that with the ICS570. The ICS571, part of IDT’s
ClockBlocks family, was designed to operate at higher
frequencies, with faster rise and fall times, and with lower
phase noise. The zero delay feature means that the rising
edge of the input clock aligns with the rising edges of both
outputs, 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.
The chip is ideal for synchronizing outputs in a large variety
of systems, from personal computers to data
communications to video. By allowing offchip feedback
paths, the ICS571 can eliminate the delay through other
devices. The use of dividers in the feedback path will enable
the part to multiply by more than two.
