This application note details when redrivers or MUX devices are needed in PCIe Gen 4 applications. The document also describes how to set up and configure the HSDC092 evaluation board with TMUXHS4412 MUX or the DS160PR421 or DS160PR412 redriver to test PCI Express® (PCIe®) Generation 4 CBB and AIC compliance test. A test report is presented and discussed.

The HSDC092 evaluation module provides a complete high-bandwidth platform for evaluating the signal-conditioning features of the DS160PR412 and DS160PR421 quad-channel PCI Express 4.0 linear redrivers. This evaluation board can be used for standard compliance testing, performance evaluation, and initial system prototyping.
The TMUXHS4412 is an analog differential passive multiplexer or demultiplexer which is P2P compatible with DS160PR412 and DS160PR421, thus HSDC092 EVM can be used to evaluate PCIe performance with TMUXHS4412 MUX as well.
