Multiplier and Zero Delay Buffer
Description
The ICS570 is a high-performance Zero Delay Buffer
(ZDB) which integrates ICS’ 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 ICS’ 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. 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.
