1. If PCM1862 uses TDM cascade, does it support 12-channel microphone input?

2.If PCM1862 uses TDM cascade, does it support 12-channel microphone input?

User,

The PCM1862 does not have TDM Cascade, or Daisy chain mode, the PCM1862 uses a standard TDM configuration.

best regards,

1.Thank you for your support ！！！I have another question，When two PCM186X-Q are cascaded, does TDM support transmission of 16bit x16 channels and sampling frequency of 96khz。

2.PCM1862-Q/PCM1863-Q does not have TDM Cascade？ PCM1864-Q/PCM1865-Q does have TDM Cascade？

Hello User,

To clarify, the images you posted above are for standard TDM mode. This is not the same as TDM cascade.

To be clear, TDM and TDM cascade are different things.

The PCM186x devices do not support cascade. The PCM186x devices do support TDM (parallel) (it would have to as there are 4 channels).

I assumed you were asking about Cascade/daisy chain mode, because it is quite clear that all of the PCM186x devices support TDM. It says this on the first page of the datasheet.

The PCM186x supports 96k operation, and can handle a bclk to LRCLK ratio of 256, but note that you would need 4 of the 4 channel PCM 186x devices to do this, and this would require an I2C mux as there are only 2 possible I2C addresses for the PCM186x.

best regards,
