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.
- STANDBY pin LOW
- MUTE pin LOW
- Write address(0x00) data(0x10) - Set PBTL mode
- Write address(0x03) data(0x44) - Set 48KHz
- Write address(0x21) data(0x80) - Clear fault
- MUTE pin HIGH
- STANDBY pin HIGH
- Write address(0x04) data(0x00)
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.
