HD3SS3220: Switching time from CC1 to CC2

Thanks for your reply.

I want to know if MUX side have a default CC pin. For example, If one of the CC pins is default, when CC of cable is connected to another CC pin, would it take time to switch?

Thank you very much.

And some problems happened when it is used to pass USB3.1 compliance test.

-When the connector is flipped, Sync Loss occurs in the loopback test.

-SyncLoss occurs when jitter is added to the signal
→ Does not occur when the amount of jitter and frequency are low

If you have met any similar cases like the above, we would appreciate it if you could give us advice on the causes and countermeasures.

And we are considering whether it is possible to take measures with devices such as retimers because of the influence of jitter.
If you have a suited retimer IC that can be used with USB3.1 Gen2, please introduce it.

Best,

Zeming

can you send the test report?

any update?

Hi Brian, 

Thanks for your follow-up.

I have asked for the report, but have not received it yet.

I think we can close this thread and I will send you via email if necessary.

Best,
