ZERO DELAY, LOW SKEW BUFFER DATASHEET ICS574 The ICS574 is a low jitter, low-skew, high performance PLL-based zero delay buffer for high speed applications. Based on IDT’s proprietary low jitter Phase Locked Loop PLL techniques, the device provides four low skew outputs at speeds up to 160 MHz at 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.

DATASHEET

ICS574

The ICS574 is a low jitter, low-skew, high performance PLL-based zero delay buffer for high speed applications. Based on IDT’s proprietary low jitter Phase Locked Loop PLL techniques, the device provides four low skew outputs at speeds up to 160 MHz at 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.
