ICS670-01

LOW PHASE NOISE ZERO DELAY BUFFER AND MULTIPLIER DATASHEET ICS670-01 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.
