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
gure shows the zSFP/zSFP+ module locaons within J29.

The detailed RFSoC connecons for the feature described in this secon are documented in the
ZCU208 board XDC le, referenced in Appendix B: Xilinx Design Constraints.
The following table lists the zSFP+ module control and status connecons.
