PI6C2509AL

Product Description

The PI6C2509-133 is a "quiet," low-skew, low-jitter, phase-locked loop (PLL) clock driver, distributing low-noise 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 5 clocks for the first bank, and an additional 4 clocks for the second bank.
