TAS2505-Q1: How to set the Echo Cancellation

Hi Kevin,

Thanks for your feedback.

I've guided to the customer that TAS2505 do not have echo-cancellation feature, but customer wants to know how to bypass the DOUT(or other alternative pins)  from the DIN.

Is this also negative?

Thanks 
Ernest

Yes, it's negative, but I think they can use the input audio to achieve it at software level.

Kevin

I've seen the Application Reference Guide(https://www.ti.com/lit/pdf/slau472 ) and this has register sets.

For below set might bypass the DIN to the DOUT, is it correct?

- Page0 / Register 53 D3:D1 set to  b’010 (= bit 010)
- Page0 / Register 52 D5:D2 set to  b’1110

Ernest

No, that's GPO configured by Reg0x53 D0, it can't bypass DIN

Kevin

Is there no way to bypass DIN to DOUT in the TAS2505?

Kevin, Thanks,

but it requires to enable secondary audio interface.

What command sequences are needed to enable the secondary audio interface?

Ernest

Kevin,

Thanks. I almost got it. 

Can I re-use BCLK and WCLK signals for primary's I2S one if the BCLK and WCLK is sourced from Processor?
Is it possible?
