Solar Express 125 (SE125), Xilinx Zynq Ultrascale+ based MPSoC half size PCIe board

SE125 is a low profile, 8 lanes PCIe card powered by the Xilinx  Zynq Utrascale+ MPSOC (XCZU7EV-2FFVC1156E / XCZU7EG/ XCZU11EG / XCZU7CG ). When XZU7EV is populated, it is capable of  video decoding/encoding, up to 8K resolution, targeting Data Center video streaming applications and with 11EG it can be a network accelerator card. SE125 offers, eight lanes of PCI Express Gen 4 ,  two  front panel USB 3.0 and one QSFP, 16 GB of DDR4 memory to PL organized as 2 independent banks of 8GB each (64 bits wide), 8GB of DDR4 to PS. Summary of devices and available resources:

x  = 7 or 11 in the case of EG only

yy = CG, or EV or EG

Z = speed grade which by default is -2 but -1 can be selected.

t = temperature grade. Default is -E which is extended but -C (commercial) or -I (industrial) can be selected
