Compatible Board
The following board is compatible with the FX2 connector on the Spartan-3E Starter Kit
board:
•
Mating Receptacle Connectors
The Spartan-3E Starter Kit board uses a Hirose FX2-100P-1.27DS header connector. The
header mates with any compatible 100-pin receptacle connector, including board-mounted
and non-locking cable connectors.
Differential I/O
The Hirose FX2 connector, header J3, supports up to 15 differential I/O pairs and two
input-only pairs using either the LVDS or RSDS I/O standards, as listed in
I/O pairs support differential input termination (DIFF_TERM) as described in the
Spartan-3E data sheet. Select pairs have optional landing pads for external termination
resistors.
These signals are not routed with matched differential impedance, as would be required
for ultimate performance. However, all traces have similar lengths to minimize skew.
