Zynq RFSoC device

The RFSoC 2x2 has a Zynq Ultrascale+ XCZU28DR-FFVG1517AAZ with an Quad-core ARM Cortex A53 Processing System (PS) and Xilinx Ultrascale+ Programmable Logic (PL). The XCZU28DR has 8x RF ADC 8x DACs. The RFsoC 2x2 board has 2x RF ADCs (4.096 GSPS) and 2x RF DACs (6.554 GSPS) available via SMA connectors.

There are BALUNs between the SMA connectors and the Zynq RFSoC on the board, which means that antenna and external signal sources can be connected directly to the board.
