PCIe x4 Connector
The Zynq Ult MPSoC Carrier board supports one PCIe x4 connector through PS-GTR Lanes of Zynq Ult
MPSoC PS. All the four PS-GTR lanes from Board to Board Connectors are connected to PCIe x4 connector to support
x1, x2 & x4 PCIe devices. The PS-GTR Lane selection to PCIe x4 connector is done through PS-GTR Lane Selection Switch
(SW5). The Carrier board provides 100MHz reference clock to PCIe x4 connector from on board Clock Synthesizer. This
PCIe x4 connector (J19) is physically located at the top of the board as shown below.
Note: For more details on PS-GTR Lane selection options, refer
