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 IDT’s proprietary
analog/digital Phase Locked Loop (PLL) techniques. The
zero delay feature means that the rising edge of the input
clock aligns with the rising edges of the outputs. There are
two identical outputs on the chip. FBCLK should be
connected to FBIN. Each output has its own output enable
pin.
The ICS670-01 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. Arbitrary multiplication factors
(including fractions) can be configured on the ICS527.
