TAS6422E-Q1: In PBTL mode, 48KHz input has silent output.

Part Number: TAS6422E-Q1

Hi,

I am developing A2B product using TAS6422E-Q1.

When I set the setting to 48KHz, there is no sound, and the sound is output at 44.1KHz.

Please see the settings below and let me know what settings I am making mistakes.

The order of setting up the TAS6422E-Q1 regiester is as follows.

The signal transmitted from the AD2428WC is as shown in the attached figure.

When this setting is made, no sound comes out.

However, except for the #4 command (set to 48KHz, default 44.1KHz), the sound is output normally.

Hi,

When in 48kHz mode, do you get a clock error fault? Monitor the fault pin to see if you get an error.

Hi,

I checked the warning pin as well as the fault pin, but it maintained a normal high.

Hi,

There was a mistake in my mind on this matter.

I ran the script to set the PBTL, but it was executed before the STANDBY pin became Low.

After adjusting the timing, the sound is output normally at the 48Khz setting.

Thanks.
