There are two types of converter tiles for the RF-ADCs, called Dual and Quad tiles. For RF-ADCs, the converters in the Dual tiles have different maximum sampling rates and different interleaving factors to the Quad tiles. Gen 1/Gen 3/DFE devices have both type of tiles, while Gen 2 devices consist of Quad RF-ADC tiles only.
Quad RF-DAC tiles are available in Gen 1/Gen 2 devices and Dual RF-DAC tiles are additionally available in Gen 3/DFE devices; the Dual RF-DAC tiles have two dedicated DUCs for each channel to support dual-band applications. There is no performance difference between converters in both types of RF-DAC tile.
|Tile Type||Number of Converters||Device Type||Notes|
|Quad RF-ADC||4||Gen 1/Gen 2/Gen 3/DFE||Each RF-ADC has an interleaving factor of four.|
|Dual RF-ADC||2||Gen 1/Gen 3/DFE||Each RF-ADC has an interleaving factor of eight, hence double the sampling rate of the converters in the Quad RF-ADC tiles.|
|Quad RF-DAC||4||Gen 1/Gen 2/Gen 3/DFE||Each RF-DAC has one dedicated DUC.|
|Dual RF-DAC||2||Gen 3/DFE||Each RF-DAC has two dedicated DUCs. For Gen 3/DFE devices featuring Quad RF-DACs or a combination of Quad and Dual RF-DACs, all tiles have external clock inputs.|
See the Zynq UltraScale+ RFSoC Data Sheet: Overview (DS889) for an overview of the maximum sampling rates and the Zynq UltraScale+ RFSoC Data Sheet: DC and AC Switching Characteristics (DS926) for the exact specifications.
The following figures illustrate the tile structures. Dashed lines indicate multiple bands cases.
