J3 interface on the Core Board
Part 2.10: Board to Board Connectors pin assignment
The core board has a total of four high-speed board to board connectors.
The core board uses four 80-pin inter-board connectors to connect to the
carrier board. The IO port of the FPGA is connected to the four connectors by
differential routing. The pin spacing of the connectors is 0.5mm, insert to the
board to board connectors on the carrier board for high-speed data
communication.
Board to Board Connectors CON1
The 80-pin board to board connectors CON1, which are used to connect
with the VCCIN power supply (+5V) and ground on the carrier board, extend
the normal IOs of the FPGA. It should be noted here that 15 pins of CON1 are
connected to the IO port of BANK34, because the BANK34 connection is
connected to DDR3. Therefore, the voltage standard of all IOs of this BANK34
is 1.5V.
