LOW PHASE NOISE ZERO DELAY BUFFER AND MULTIPLIER
Description
The ICS670-04 is a high speed, low phase noise, Zero
Delay Buffer (ZDB) which integrates IDT’s proprietary
analog/digital Phase Locked Loop (PLL) techniques. It is
identical to the ICS670-02, but with an increased maximum
output frequency of 210 MHz. 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 ICS670-04 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.
