Forum Post: RE: How to feed data to Tx in ADRV9009 project. I found the correct way to give data in this post: https://ez.analog.com/sw-inter....face-tools/f/q-a/103 " The channels for TX on the ADRV9009 are from 0 to 3, dac_data_0 being I0, dac_data_1 Q0, dac_data_2 I1 and dac_data_3 Q1. the DAC_DATA buscomes from the DMA. Each of the 32 bit dac_data_x bus has two consecutive samples for the channel so if you want to send IQ data for the RF channel 0, you'll need to provide data on the dac_data_0 and dac_data_1 buses.
