The Renesas Electronics 9DB833 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1. The 9DB833 is driven by a differential SRC output pair from an IDT 932S421 or 932SQ420 or equivalent main clock generator. 3 selectable SMBus addresses multiple devices can
share the same SMBus segment
OE# pins suitable for Express Card applications
PLL or bypass mode PLL can dejitter incoming clock
Selectable PLL bandwidth minimizes jitter peaking in
downstream PLLs
Spread spectrum compatible tracks spreading input
clock for low EMI
