KC705 Evaluation Board
55
UG810 (v1.3) May 10, 2013
Feature Descriptions
Connector Type:
•
Samtec SEAF Series, 1.27 mm (0.050 in) pitch. Mates with SEAM series connector
For more information about SEAF series connectors see
HPC Connector J22
[
, callout
The 400-pin HPC connector defined By the FMC specification (
provides connectivity for up to:
•
160 single-ended or 80 differential user-defined signals
•
10 GTX transceivers
•
2 GTX clocks
•
4 differential clocks
•
159 ground and 15 power connections
The connections between the HPC connector at J22 and FPGA U1 (
) implement a
subset of this connectivity:
•
58 differential user defined pairs
•
34 LA pairs (LA00-LA33)
•
24 HA pairs (HA00-HA23)
•
4 GTX transceivers
•
1 GTX clock
•
2 differential clocks
•
159 ground and 15 power connections
The HPC signals are distributed across GTX Quads 116, 117, and 118. Each of these Quads
have their VCCO voltage connected to VADJ.
Note:
The KC705 board VADJ voltage for the J22 and J2 connectors is determined by the FMC
VADJ power sequencing logic described in the
.
