PCM9211: PCM9211 Non Pcm Detection enquiry

TBK

Part Number: PCM9211

PCM9211 having Non Pcm detection feature, may I know if input below format, the Non-PCM detection will activate and output flag to the PCM9211 interrupt port?

Yes if you set above register to detect than set either int0 or int1 mask and output registers to cause interrupt on error condition then it will. below are registers of int0 for guidance

Hi Carson ,

Thank you for your advice.

As I have limited DTS/Dolby /others non pcm source to verify the function non pcm detection. May I know TI have verify all type of non pcm source that available in the market input to pcm9211 to check non pcm detection able to react accordingly or not?

Hello,

Sorry that is something I cannot absolutely verify since there is such a variety.

Hi Carson,

May I the PCM9211 non pcm detection can react when inputted multichannel PCM data? ( means PCM9211 can differentiate stereo PCM / multichannel PCM?)

TBK,

Carson is currently out of the office until Friday and he can get back to you at that time. From my interpretation of the datasheet, the non-PCM detection is based solely on these two methods:

1. Channel Status Bit 1 is 1

2. A Burst Preamble (PA/PB) is found in the S/PDIF stream

Thanks,

Brian

It will accept stereo PCM but will error on multichannel PCM

when receive multichannel PCM, it will trigger the Non PCM flag?( when receive multichannel PCM, can it be trigger the PCM9211 interrupt port?)

Hello,

This snippet from page 18 of the datasheet would be best to read through to answer your question

Best Regards,
