About AP1_OUT of ADV7625

Hi.

Please tell me about ADV7625.

I set the AP1_OUT port pins individually using the tristate_ap1_out_x [7:0] control register.

I'd like to use the AP1_OUT4 port, but the port couldn't communicate as I2S data.

The AP1_OUT port 0 and 1 were working as I2S data and I could measure their waveform.

Could you help me?

Best Regards

  • Hi,

      'AP1_OUT4' should output I2S data , Please make sure whether you are in I2S mode.

       

    Also make sure this corresponding bit - TRISTATE_AP1_OUT_X[4] = Tristate AP1_OUT[4] pin should be '0' in register TRISTATE_AP1_OUT_X[7:0] (0x9D).

    Thanks,

    Hi.

    Thank you for your answer.

    I checked out I2S mode for AP1_OUT4 port but I didn't confirm the waveform as I2s data.

    I understand that Tristate AP1_OUT[4] pin should be '0' in register.

    Which device address is 00 or EC?

    I executed in the following steps.

    ①used script file (ADV7625-26-27_Ver1.0)

    ②selected HDMI Splitter Mode 

    ③set Tristate AP1_OUT_X

    ④set I2S out mode

    Best Regards
