In my opinion, the "M" of Modes #7 in Dual Link should be "2", not "4" as in Single-Link. Can you confirm?
(Pls refer to the Table 15 and Table 16 on page 30 of AD9173 Datasheet)
Thank you for your comment. The difference between dual and single-link modes is that in the former case (dual-link) there are two independent links are established. You would have two sets of JESD204B parameters, and two "M's" for each link, each with a value of 4. Note that the parameters for both links must be identical for clocking requirements, but each link has its own syncout-bar pin to set and reset the link independently from the other.
To put it simply, [dual-link] == [2x single link] for a given mode.
As a sidenote, note that the only modes that support dual-link are the ones with L<=4, since there are a total of 8 lanes available on the AD917x. for example, compare mode 8 with mode 10, and mode 9 with mode 11: modes 8,9 allow dual-link at the expense of lower datarate relative to modes 10,11. The only difference is the number of lanes used.
I hope this helps.
That makes good sense! Grateful to Arik!
