The data streams represent real or I/Q data, depending on the RF-DAC tile configuration. For RF-DAC tiles, a given stream is either real or I/Q interleaved. If an RF-DAC is configured with I/Q input data then the even numbered samples of the stream represent I data and the odd-numbered samples represent Q data. These real and I/Q configurations are shown in RF-DAC IP Configuration.

In each configuration all the enabled RF-DAC FIFOs in a tile begin to accept data when the power-up sequence has completed. This is indicated by the assertion of the sXY_axis_tready outputs. If the data for any stream is not valid at this point, logic to suppress it should be included in the PL.The RF-DAC does not use the sXY_axis_tvalid input to gate the data.
