TMUXHS4212: Cascaded implementation

Part Number: TMUXHS4212

Tool/software:

Hello Team,

Our SoC supports a single lane PCIe Gen-2 lanes and we need to validate following features via same

1. NVMe support

2.WiFi/BT support via LGA module

3. A PCIe daughter card support

To achieve this, I am planning to implement a MUXing option for the PCIe lanes to derive the said feature support.

The table refers to how the MUX selection to be done for getting the said features

Can I proceed with this kind of implementation?

Is incorporation of multiple MUXes results in any kind of SI issues?

Can I use resistor bypassing option in place of MUX-2? Is this recommended?
