Overview

The RC19020 is a 20-output PCIe Gen7 buffer that is backward compatible with earlier PCIe generations. The RC19020 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.

RC19020 is also pin-compatible to DB2000Q/DB2000QL plus adding Loss-Of-Signal (LOS) indication and an SBI_OUT pin for multiple clock chip daisy-chain.
