FX3 DVK Interconnect Boards
Three interconnect boards are available to interface the FX3 GPIF II (using the Samtec connector,
J77) to external devices.
■
FMC interconnect board: Connects Xilinx FPGA development board to the FX3 DVK.
■
HSMC interconnect board: Connects Altera FPGA development board to the FX3 DVK.
■
Aptina interconnect board: Connects Aptina image sensor headboard to the FX3 DVK.
How do I get an interconnect board?
Contact Cypress at
to obtain an interconnection board.

Reset Circuit
The FX3 device can be reset either from an external processor wired to the Samtec connector or
from an on-board push button. This selection can be made on J72; see
Figure 4-12
.
Figure 4-12. Reset Circuit and Selection Headers
Based on the jumper setting on J72, either this RESET_N signal goes to the FX3 device (J72 pins 1
and 2 connected) or a signal from the external processor resets the FX3 device (J72 pins 2 and 3
connected).
