The VCU1287 board features two high pin count (HPC) connectors as defined by the VITA
57.1 FPGA Mezzanine card (FMC) specification. The FMC HPC connector is a 10 x 40 position
socket. See
Appendix B, VITA 57.1 FMC Connector Pinouts
for a cross-reference of signal
names to pin coordinates.
The FMC1 HPC connector JA2 provides connectivity for:
• 75 differential user defined pairs:
°
34 LA pairs
°
24 HA pairs
°
17 HB pairs
• 4 differential clocks
The FMC2 HPC connector JA3 provides connectivity for:
• 20 differential user defined pairs:
°
20 LA pairs
• 2 differential clocks
The FMC3 HPC connector JA4 provides connectivity for:
• 80 differential user defined pairs:
°
34 LA pairs
°
24 HA pairs
°
22 HB pairs
• 4 differential clocks
IMPORTANT:
The V
ADJ
voltage on the FMC1 and FMC3 HPC connectors tracks VCCO_HP. While the
V
ADJ
voltage on the FMC2 HPC connectors tracks VCCO_HR.
