TAS5548/58 SDOUT Mode

Sadanori Kato

Hi,

Could you please give us your advice for the sdout mode ?
We understand that we can select an valid data(48kHz only) as the sdout if setting the D8 and D9 of the 0xC5 which is the ASRC mode control register.
So, would you share the processing flow for those mode ?
Moreover, does "Select DAP output for serial out" mean "Dolby Downmix" as below ?

Best regards,

Hi Kato-san,

As for the Table header, yes this is a typo, it should be a repeat of the D15-D8.

As for the SDOUT signal path, selecting DAP output for serial out means that it will pass though the Dobly down mix mixers. If you select ASRC channels 1+2 or 3+4 this means the channel input will go directly to the output without passing through the Dolby down mix mixers.
