Product Description
The PI6C2504 features a low-skew, low-jitter, phase-locked loop
(PLL) clock driver, distributing high-frequency clock signals for
SDRAM and server applications. By connecting the feedback
FB_OUT output to the feedback FB_IN input, the propagation
delay from the CLK_IN input to any clock output will be nearly zero.
