Part 10: FMC Expansion Port
The AXKU040 FPGA development board comes with two standard FMC
LPC expansion ports and one standard FMC HPC expansion ports that can be
connected to various FMC modules of XILINX or ALINX (HDMI input and
output modules, binocular camera modules, high-speed AD modules, etc.). The
FMC expansion port contains 33 pairs of differential IO signals and one I2C bus
signal.
The LPC FMC1 expansion port has 33 pairs of differential signals, which
are respectively connected to the IO of BANK47 and BANK48 of the FPGA chip.
The IO level of BANK47 and BANK48 is 1.8V and cannot be modified. The 1
pair speed GTH transceiver signal is connected to BNAK226.
The LPC FMC2 expansion port has 33 pairs of differential signals, which
are respectively connected to the IO of the BANK64 and BANK65 of the FPGA
chip. The level standard is determined by the voltage VADJ of the BANK, and
the default is +1.8V. The voltage of VADJ can be configured by the program to
change the output voltage of the PMIC chip LP873220. The 1 pair speed GTH
transceiver signal is connected to BNAK226.
The FMC HPC expansion port contains 57 pairs of differential IO signals,
which are connected to FPGA chips BANK66, BANK67, BANK68, and the
voltage standard is 1.8V. 8 high-speed GTH transceiver signals are connected
to the IO of the FPGA chip BANK227 and BANK228.
The schematic diagrams of FPGA and FMC LPC connectors are shown in
