7.5. MIPI/Pcam Ports
The two MIPI/Pcam ports included on the Genesys ZU are 15‐pin, 1 mm pitch, zero insertion force (ZIF)
connectors designed specifically for attaching camera sensor modules to host systems. It builds on the
Pcam connector standard introduced on the Digilent Zybo Z7, but allows for bi‐directional D‐PHY lanes
thanks to direct I/O support in the UltraScale+ architecture. Therefore, it supports MIPI DSI applications
too, while remaining backward compatible with MIPI CSI‐2 Pcam modules, like the Digilent Pcam 5C.
The Pcam connector pin‐out is rigidly defined and includes a two lane MIPI CSI‐2 bus for camera data, an
I2C bus for camera configuration, two additional general purpose signals, and 3.3 V for powering the
camera module, as depicted in Figure 7.5.1 and Table 7.5.1. Digilent is developing a catalog of Pcam
peripheral camera modules with various different types of sensors that all conform to this pin‐out. The
pin‐out was also chosen so that many camera modules designed to work with the Raspberry Pi will also
work when connected to the Pcam port.
