Hello,

My customer would like to know how to configure JESD204B Frame Format for LMFSHd = 82380 on the GUI.
Please show how to do that step by step.

Hirano-san,

Do they plan on using the device in Wideband-DUC mode?

Hirano-san,

Attached is a GUI example setup. This is not Wideband-DUC mode. This mode requires two clock sources that are synchronized to each other. The other document explains the Frame Format.

Jim

Thank you for your responses.

Jim,

Thank you very much for providing the slides.
But, my customer would still like to know how to set the portion framed in red below, between SerDes input and I/Q data streams
Could you provide some instructions, please?

Best regards,

Hirano-san,

See if the attached document helps. The user will send 4 lanes of real data to DUC 1 (I data) and 4 lanes of real data to DUC 2 (Q data). The lanes are swapped on the DAC38RF82EVM GUI setting since they are routed this way on the PCB.

Regards,

Jim
