The Renesas Electronics 9DB433 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1. The 9DB433 is driven by a differential SRC output pair from an IDT 932S421 or 932SQ420 or equivalent main clock generator. Output cycle-cycle jitter <50ps
Output to Output skew <50ps
Phase jitter: PCIe Gen3 <1.0ps rms
