Description
The ICS574 is a low jitter, low-skew, high performance PLL-based zero delay buffer for high speed applications. Based on ICS’s proprietary low jitter Phase Locked Loop (PLL) techniques, the device provides four low skew outputs at speeds up to 160 MHz at 3.3 V. When one of the outputs is connected directly to FBIN, the rising edge of each output is aligned with the rising edge of the input clock. External delay elements connected in the feedback loops will cause the outputs to occur before the inputs by the amount of propagation delay of the external element.
ICS manufactures the largest variety of clock generators and buffers, and is the largest clock supplier in the world.
