The 2402 is a high-performance Zero Delay Buffer (ZDB) which integrates IDT's proprietary analog/digital Phase-Locked Loop (PLL) techniques. The chip is part of IDT's ClockBlocksTM family and was designed as a performance upgrade to meet today's higher speed and lower voltage requirements. The zero delay feature means that the rising edge of the input clock aligns with the rising edges of both output clocks, giving the appearance of no delay through the device. The 2402 is ideal for synchronizing outputs in a large variety of systems, from personal computers to data communications to graphics/video. By allowing off-chip feedback paths, the device can eliminate the delay through other devices.
