FMC HPC Connector J22
[Figure 1-2, callout 33]
The 400-pin HPC connector defined by the FMC specification (Figure B-2) provides
connectivity for up to:
• 160 single-ended or 80 differential user-defined signals
• 10 GTH transceivers
• 2 GTH clocks
• 4 differential clocks
• 159 ground and 15 power connections
The HPC connector at J22 implements a subset of the full FMC HPC connectivity:
• 58 differential user-defined pairs (34 LA pairs: LA[00:33]; 24 HA pairs: HA[00:23])
• 8 GTH transceivers
• 2 GTH clocks
• 2 differential clocks
• 159 ground and 15 power connections
The FMC DP[7:0] transmit and receive signal data paths are routed with a differential
characteristic impedance of 100Ω (±10%) with an insertion loss of <4 dB up to 8 GHz. The
KCU105 board FMC VADJ voltage VADJ_1V8 for the J22 and J2 FMC connectors is sourced
by the MAX15301 U30 voltage regulator described in
