PCM9211: Behavior When PCM9211 Detects DIR Errors

Sadanori Kato

Part Number: PCM9211

Hi,

The ADC output is routed to the Main Output Port automatically after the wait time which is set to XTIWT[1:0] when the DIR is unlocked, so could you please tell me whether ADC output is routed to the Main Output Port even if setting 200ms to XTIWT[1:0] when the DIR is unlocked for only a short time(e.g. : 1ms) ?
I expect that the output will not be changed in above case.
In addition, could you please tell me the detailed detection algorithm that the DIR detects unlocking ?

Best regards,
Kato

Hi Kato-san,

Since PCM9211 was designed in another TI location and some of the designers have relocated and working for other team, we are having some difficulty getting the design details for DIR block in timely fashion. We apologize for not being able to give timely answer.

Ajit (Apps Manager) is helping me w. this and we will try to get you the answer as soon as we can. Thanks.

Best regards,
Ravi

Hi Ravi-san,

Please let me know if you have any updates on these questions.
Because it takes a long time to obtain the answer, there is a possibility that this socket will be lost.
