Description

The PI6C2510-133 is a “quiet,” 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. This zero-delay feature allows the CLK_IN input clock to be distributed, providing one clock input to one bank of ten outputs, with an output enable.

This clock driver is designed to meet the PC133 SDRAM Registered DIMM specification. For test purposes, the PLL can be bypassed by strapping AVCC to ground.
