In my case if we wanted to send two streams each at 1Gbps rates with interpolation of either 2 or 4, are the only possible JESD modes 8 or 9? If so, would the lane rate be (2/4)*16*(10/8)*1 = 10Gbps? (4 lanes for each stream)

Hi,

Apologies for the delay. Yes, for a dual-link JESD mode (two separate JESD links, L=4 for each) and interpolation>1, modes 8 or 9 are the ones to use. Table 13 in the datasheet provides a summary.

the lanes rate is correct,

*assuming*that you can adjust the DAC clock to match your desired datarate.The fastest way to get started with the AD9172 is using an Eval board (EVB) and the ACE software, which would also give you the datarate, lanerate, and other information based on the configurations you select.

Happy experimenting!

Best Regards,

Arik
