Board Technical Description
1. VITA 57.1 FMC HPC Connector J17
This connector provides the interface to the board containing the Xilinx FPGA. The XM105 
uses Samtec FMC HPC connector part number ASP-134488-01. The XM105 connector 
mates with a FMC LPC connector or an FMC HPC connector on Xilinx boards. 
Table 1-3 shows the VITA 57.1 FMC HPC pin assignments, associated schematic signal 
names, and XM105 header or connector to which the signal is wired. Pins labeled as 
no connect are not used on the XM105. Board FPGA signals are wired to various headers 
and connectors on the XM105. Subsequent sections define each connector, including a 
connection table showing FMC HPC to breakout connector wiring. Xilinx boards listed in 
Table 1-3 provide fixed 2.5V power to VADJ pins of the FMC HPC connector.
