Hello,
I am using the PCM1795 and I am supplying clocks and data but don't get an analog output. All analog outputs are at a current of -1.2mA no matter the digital input. Some more parameters of my setup:
* 32bit, right-justified format
* SYCLK = 5MHz
* BCK = 1.25MHz
* LRCK = 19.53125kHz (Note: _not_ an audio application so non-standard sample rate.
* All clocks verified using logic analyzer
* All registers in their default state except register 18 where I set FMT to 001
** I can read back the register contents periodically and the values are correct.
** If I send 0x9200 to the control port I get back 0x0010.
* Reset conditions have been checked. Delay between reset and configurationis long enough. Configuration is kept so assumed OK.
* All power supplies within +-1% of nominal
How can I proceed debugging this issue? Is there any way to read out the status of the baudrate auto-detect?
Best regards,
Matthias
