描述
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.
