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