The HSPC connector J26 implements a subset of the full FMCP connectivity:
• 68 single-ended or 34 differential user-defined pairs (34 LA pairs: LA[00:33])
• 12 transceiver differential pairs
• 3 transceiver differential clocks
• 2 differential clocks
• 239 ground and 16 power connections
The FMCP HSPC J26 connections to RFSoC U1 are referenced in Design Constraints . See the FPGA Mezzanine Card (FMC) VITA 57.4 specification [Ref 24] for additional information on the FMCP HSPC connector.
