ICS670-01
Low Phase Noise Zero Delay Buffer and Multiplier
Description
The ICS670-01 is a high speed, low phase noise
Zero Delay Buffer (ZDB) which integrates ICS’
proprietary analog/digital Phase Locked Loop
(PLL) techniques. Part of ICS’ ClockBlocks
family, the zero delay feature means that the rising
edge of the input clock aligns with the rising edges
of the outputs, giving the appearance of no delay
through the device. There are two identical outputs
on the chip. The FBCLK should be used to
connect to the FBIN. Each output has its own
output enable pin.
The chip is ideal for synchronizing outputs in a
large variety of systems, from personal computers
to data communications to video. By allowing off-
chip feedback paths, the ICS670-01 can eliminate
the delay through other devices. The 15 different
on-chip multipliers work in a variety of
applications. For other multipliers, including
fractional multipliers, see the ICS527.
