Xilinx Zynq UltraScale+ ZCU208 User Manual page 47

The ZCU208 board hosts a quad zSFP/zSFP+ connector (J29) that accept zSFP or zSFP+
modules. The connectors are housed within a single 2x2 zSFP cage assembly. The following
figure shows the zSFP/zSFP+ module locations within J29.
The detailed RFSoC connections for the feature described in this section are documented in the
ZCU208 board XDC file, referenced in
The following table lists the zSFP+ module control and status connections.
