Clocks & Timing

Overview

The RC19202 is a 2:2 PCIe Gen6 multiplexer that is backward compatible to earlier PCIe generations. The RC19202 provides ultra-low additive jitter and reduced in-to-out delay performance for better design-margin and incorporates several features for easier and more robust design.
