The Samtec connector system is rated for signaling speeds up to 9 GHz (18 Gb/s) based on
a -3 dB insertion loss point within a two-level signaling environment.

The 400-pin HPC connector defined by the FMC specification
provides connectivity for up to:
•
•
•
•
•
The connections between the HPC connector at J22 and FPGA U1
subset of this connectivity:
•
•
•
•
•
The HPC signals are distributed across GTX Quads 116, 117, and 118. Each of these Quads
have their VCCO voltage connected to VADJ.
