PCM6360-Q1: All channels are in a Power down state

Part Number: PCM6360-Q1

Tool/software:

We are currently using the PCM6360-q1.pdf chip model.
The parameters were set according to the manual. The current mode used is IIC communication, and the communication address is 0x90.

90 02 01
90 28 10
90 3C 18
90 41 18
90 46 18
90 4B 18
90 73 F0
90 74 F0
90 75 E0
After setting, perform register reading.

[addr:0x7f] data:[00][00][00][00][00][00][00][00]
The content set by 0x75 is E0, but the status register 0x76 is 00 and 0x77 is C8
All channels are in a Power down state.

The Adc of all channels is in a turn off state.

We need to confirm why the status is still in power down state after setting.
Do you need to confirm the status of any other registers again.
  • Hi,

    Per the readback that you have shared, the register 0x15 (ASI_STS) is reading 0xFF, indicating invalid sample rate.

    [addr:0x0f] data:[04][05][06][07][02][48][ff][10]

    Additionally, the register 0x2C is indicating ASI clock error.

    [addr:0x27] data:[00][10][ff][03][00][80][00][00]

    Can you confirm that valid BCLK and FSYNC signals are being given to the device while checking the status?

    Thanks and Regards,
