Hi, ADI friends


Please see below picture, for Tx channel, we have four data input channels from DMA:

dac_data_i0[31:0] & dac_data_q0[31:0] & dac_data_i1[31:0] & dac_data_q1[31:0]


And one output channel to JESD204B IP core:



My question is : how to map dac_data_i/q data map to dac_tx_data ?

dac_tx_data[127:96] -> dac_data_q1[31:0] ?

dac_tx_data[95:64] -> dac_data_i1[31:0] ?

dac_tx_data[63:32] -> dac_data_q0[31:0] ?

dac_tx_data[31:0] -> dac_data_i0[31:0] ?
