Description

The ICS570B is a high performance Zero Delay Buffer (ZDB) which integrates ICS' proprietary analog/digital P ase Locked Loop (PLL) techniques. The ICS570B, part of ICS' ClockBlocks™ family, 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 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 device incorporates an all-chip power down/tri-state mode that stops the internal PLL and puts both outputs into a high impedance state.

The ICS570B 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.

The ICS570B was done to improve input to output jitter from the original ICS570M and ICS570A verisons, and is recommended for all new 3.3 V only designs.

For 5V applications, use the ICS570A.
