The DINAR1_Intercon is a daughter card that bridges the expansion signals between two 400-pin DINAR1 expansion connectors, adding 75 pairs of LVDS signals for FPGA to FPGA interconnect. At a lower frequency, the 75 pairs can be used as 150 signal-ended signals. Linear regulators needed to drive the VccI/O voltages are provided, along with several LEDs for power presence and reset activity. The expansion board is compatible with applicable DINAR1 connectors on the following Virtex-7 based products: DNV7F2A, and DNV7F4A.
