The ICS570-01 is a high-performance Zero Delay Buffer (ZDB) which integrates IDT's proprietary mixed signal Phased Lock Loop (PLL) techniques. The zero delay feature means that the rising edge of the input clock aligns with the rising edges of the output clock, giving the appearance of no delay through the device. The device includes an on-chip ROM table with nine different mulitplication factors, allowing it to generate many common output frequencies from a single input.
