PCM1862: Change from PCM1864 - DOUT2 not working any more

Daniel Wohlmuth
Prodigy 40 points
Part Number: PCM1862
Other Parts Discussed in Thread: PCM1864,

Hello,

I changed from the PCM1864 to the PCM1862. Analog input pins 1L and 1R are used and muxed to the first Audio ADC, but both Digital outputs DOU and DOUT2 are used. When using the PCM1864 the DOUT2 is working, when using the PCM1862 the DOUT2 is not working without changing the software. But I can not find a difference in datasheet concerning the DOUT2 pin.

I use it in I2S mode, not TDM

GPIO3 is set to DOUT3.

I Set the mixer 1, 2 and 3, 4 to AD Output 1L and 1R similar.

Is there anything I am missing or are there restrictions of DOUT2 in the PCM1862?

Best regards,

Daniel
