DDC112: Diasy-Chaining DDC112

Other Parts Discussed in Thread: DDC232

When daisy-chaining DDC112s, do all of the DVALID signals need to be monitored to ensure that they have all completed the data conversion cycle, or monitoring one DVALID is sufficient.

Thank you

Hi Tony,

Thanks for the post.

For daisy-chain mode, monitoring one DVALID is sufficient for data retrieval purposes. Please refer to the thread below for more information on some recommendations using daisy-chain mode. It is specifically for DDC232, but the discussion is also applicable for DDC112 as well.
