AFE7444EVM: Problems with AFE7444EVM KCU105 example design

Part Number: AFE7444EVM
Other Parts Discussed in Thread: TI-JESD204-IP

AFE7444evm: I am simulating the example design provided by TI for the KCU105 and I cannot understand why there is nothing out of channel A, despite the fact that in the code a sine wave is emitted from all channels. What is the reason?

Hi Andrea,

Are you simulating the FPGA reference design or did you setup an AFE7444EVM connected to KCU105 and checking DAC channel A output? Please clarify. If there's no hardware setup, you can't truly simulate channel A output unless DAC is modelled. Only up to FPGA JESD output lanes can be simulated.

Also note that this is a relatively older reference design. TI now offers TI-JESD204-IP with many reference designs. You can refer to it here: https://www.ti.com/tool/TI-JESD204-IP

Regards,

Vijay
