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)

Thanks!

Hi Vicky,

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.

Best Regards,

Arik
