Does TS5A22362 support UART TX/RX signal？

Jacky,

Yes the TS5A22362  can support UART TX/RX signal, due to connect to debug interface but is probably not the best solution in our portfolio for this application.  The TS5A22362 can work as long as the UART signal bandwidth and voltage level remain within the recommended operating conditions of the TS5A22362.  The UART signal should be less than 17MHz and no greater than the supply voltage of the TS5A22362.

I would recommend using the TS5USBA224 for this type of audio and UART switching application.   The TS5USBA224 is widely used among our customers in the application you describe. 

Thank you,

Adam
