9DML0451 Overview
The 9DML0441 and 9DML0451 devices are 3.3V members of Renesas' Full-Featured PCIe family. They support PCIe Gen1 6 mon Clocked (CC), Separate Reference no Spread (SRnS), and Independent Reference (IR) clock architectures. The parts provide a choice of asynchronous or glitch-free, gapped-clock switching modes, and offer a choice of integrated output terminations for direct connection to 85Ω or 100Ω transmission lines.
