ICS571
Description
The ICS571 is a high speed, high output drive, low phase noise Zero Delay Buffer (ZDB) which integrates IDT’s proprietary analog/digital Phase Locked Loop (PLL) techniques. IDT introduced the world standard for these devices in 1992 with the debut of the AV9170, and updated that with the ICS570. The ICS571, part of IDT’s ClockBlocks™ family, was designed to operate at higher frequencies, with faster rise and fall times, and with lower phase noise. The zero delay feature means that the rising edge of the input clock aligns with the rising edges of both outputs, giving the appearance of no delay through the device. There are two outputs on the chip, one being a low-skew divide by two of the other.
The chip is ideal for synchronizing outputs in a large variety of systems, from personal computers to data communications to video. By allowing offchip feedback paths, the ICS571 can eliminate the delay through other devices...
