Part Number: PCM1753

I would like to set a register of pcm1753 using spi communication

Is there an example related to this?

GeonHee,

The exact conditions depend on what configuration you require in your system. By default, the PCM1753 is configured as shown below:

If you require other configurations, you will need to address those registers.

Thanks,

Paul

SPI communication waveform to set register20.

However, the format of PCM1753 does not change.

I need to use a 16bit right-justufued data format.

Can you find a problem?

Hi,

That waveform looks correct to me. Can you confirm that the device is correctly powered? What frequency is your SCK, LRCK, and BCK?

Thanks,

Paul

Do you need SCK,LRCK,BCK waveforms?

Unfortunately, I2S-related waveforms cannot be measured.

However, when tested using PCM1754 on the same board, the wave file output was smooth.

After changing to PCM1753, it is not outputted.
