Description

LOW PHASE NOISE ZERO DELA
The 571M 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. ICS introduced the world standard for these devices in 1992 with the debut of the AV9170, and updated that with the ICS570. The 571M, 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 571M 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.
