The PCI Express transmit lanes are AC coupled (DC blocking capacitors are included in the
signal path) on the baseboard as required by the PCI Express specification.

– GTX Pin Assignments for PCI Express
2.2.2.1
PCI Express Configuration Timing
The Zynq 7Z045 Mini-Module Plus Development Board meets the 200 ms configuration
time requirement for ATX based PC systems when configuring from the QSPI interface.
2.2.3
GTX for FMC Expansion Connector, SFP, Display Port and SMA (Baseboard)
Four other high-speed gigabit interfaces from the Mini-Module Plus Baseboard 2 are connected
to the 7Z045 via the JX1 connector. Each interface is one lane wide and all reside on bank 109
of the 7Z045.
One GTX transceiver port is connected to the baseboard’s FMC LPC connector. The FMC
LPC connector has one gigabit lane dedicated to it for use with FMC daughter cards.
One
GTX transceiver port is connected to the baseboard’s SFP interface.
One GTX transceiver port is connected to the baseboard’s SMA interface.
One GTX transceiver port is connected to the baseboard’s Display Port interface (TX only).
