Verify retimer device compliance to USB4

High-speed digital communications systems require retimers to maintain signal strength. These devices extract the embedded clock signal from a high-speed protocol, fully recover the data, and re-transmit a fresh copy of the data using a clean clock. Retimers are mandated in the USB4 standard. A key difference between testing past USB devices (3.2x1) and testing USB4 devices is their specific retimer capabilities. Often used in sequences in USB4, retimers increase test complexity.

Compliance test must include verification of both bit-level retiming (BLR) and separate reference clocks with independent SSC (SRIS) clocking modes. Using high-performance test equipment capable of handling high-speed digital signals with USB4 software templates is one way to simplify and speed verification of compliance of retimer devices to the USB4 standard.
