Integrated Device Technology Low Phase Noise Zero Delay Buffer and Multiplier 670M-04ILF

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 .
