Hi Harry,

Your ticket has two part numbers listed. Can you clarify if you're talking about the PCM1861-Q1 or PCM1681-Q1?

Thanks,
Jeff McPherson

Hi Harry,

In section 8.3.4 of the datasheet, it says that the device supports TDM8, and is only supported in the multiples 128, 256, and 512fs. TDM8 is much more typical and friendlier to the clock set up. TDM6 would be possible only if the clocking was setup for TDM8 and the last two channels are blank.

Best regards,
Jeff McPherson
