KCU1250 Board Features and Operation
FPGA Mezzanine Card HPC Interface
The KCU1250 board features three high pin count (HPC) connectors as defined by the VITA
57.1 FMC specification (callout 28, 29 and 30,
). 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:
• 43 differential user defined pairs:
°
34 LA pairs
°
9 HA pairs
• 4 differential clocks
The FMC2 HPC connector JA3 provides connectivity for:
• 44 differential user defined pairs:
°
34 LA pairs
°
10 HA pairs
• 2 differential clocks
The FMC 3 HPC connector JA4 provides connectivity for:
• 45 differential user defined pairs:
°
34 LA pairs
°
11 HA pairs
• 2 differential clocks
IMPORTANT:
The VADJ voltage on the FMC HPC connectors tracks V
CCO_HP
