Hi,

Sorry for correct informtion, my require is I2S 1:2 but can output at the same time.

Does TI have this kind of solution?

Or I2S can parallel two output without any switch is fine?

In general, routing one output to several CMOS inputs is no problem. (If you suspect that the load becomes too high, you can add buffers.)

You need some kind of switch or demultiplexer only if you want to disable one of them.

Hi Jeff,

I suggest using the TS5A23157-Q1. It is a 1;2 device and has 2 channels which means it can output two signals at the same time.

Here is an FAQ that talks about I2S in more detail.

Please let me know if you need any further assistance!

Thanks and Regards,

Kameron
