[FAQ] AM6442: Running Raw Serdes

Tony Spagnolia

Part Number: AM6442

Tool/software:

We have a desire to use the SERDES as a raw interface without a protocol on top. The idea would be to just run 8b/10b and limit our packet size to 10 -40 bits. Is this possible or do we need to run PCIE or USB using the PCS?

Hello Tony Spagnolia

Thank you for the query.

I am aware of the PCIe or the USB3 use cases that has been enabled.

Let me check the feasibility and update you.

Hello Tony Spagnolia

Please refer below inputs i received from the expert:

Customer should implement the interface as-intended and as-tested. In this case, that’s PCIe or SuperSpeed USB. Anything else is not supported.
