Hello Bob or someone else,
I have a question regarding the daisy-chained connection of DDC264, regarding Figure 28 and Figure 29 in the DDC264 spec (SBAS368C –MAY 2006–REVISED JULY 2011) in page 17. In Figure 29, there is a DVALID signal, and in Figure 28, there are four DVALID pins from four connected converters; which DVALID pin (out of four) of Figure 28 does the DVALID signal in Figure 29 refer to?
How do I use these four DVALID pins correctly in the daisy-chain connection?
Thank you,
Ron

Hello Ron,
Please look at the attached file with the boad schematic.
On the page #3, it shows only DVALID pin of the left DDC264 is connected to Xilinx Spartan
(called DAVLIDn1).
Other DVALID pins of other DDC264s are floating.
