Danf,
We got the evaluation board for the chip AD9748, and I have a question about the input pins of the digital bits (DB0X-DB7X).
In page 19 of the spec sheet of the AD9748 it indicates that the inputs in the "header" for DB0-7X are pins 27, 25, 23, 21, 19,17, 15 and 13, and DB0-7X are directed to the Digital bit inputs of the chip DB0-7. However, by looking at the evaluation board layout in page 21, these pins do not go to the right pin input of the chip, as described in page 7. Instead, it looks like to me that the "header" inputs corresponding to DB0-7X should be 15, 13, 11, 9, 7, 5, 3, 1, where the MSB (DB7) is pin 1.This would match the evaluation board layout and the in configuration of the chip in page 7.
Could you please tell me if this is correct?
Thank you
