FMC Expansion Connector #2
Samtec ASP-134603-01. The FMC expansion connector #2 (J19) follows the VITA 57.1
FMC standard and is used in low pin count (LPC) format. It can either be used to
accommodate a single width FMC Module or one dual FMC Module when used in
conjuncture with FMC expansion connector #1 (J13). See
“FMC Expansion
Connectors”
for detailed information.
Note
: The FMC connector #2 has its own adjustable power supply to provide the
appropriate voltage to the FPGA bank used to communicate with the FMC module.
Make sure that the FMC adjustable power supply is configured for the voltage
specified by the FMC module. See
“FMC Expansion Connectors”
for instructions
about how to properly configure the adjustable power supplies.
