ICS670-02
LOW PHASE NOISE, ZERO DELAY BUFFER AND MULTIPLIER
Description
The ICS670-02 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’ ClockBlocksTM family, the part’s 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.
www.DTahtaeShICeSet647U0.c-o0m2 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 chip can eliminate the delay
through other devices. The 15 different on-chip
multipliers work in a variety of applications. For other
multipliers, including functional multipliers, see the
ICS527.
