(十) Board-to-Board Connector
The core board has four high-speed board-to-board connectors on PCB
bottom side. Each connector is 80-pins of 0.5mm pin pitch, which is suitable for
high-speed signal transmission. 180 FPGA IOs (include 86 pairs LVDS signals)
and all differential signals of GTP transceivers are connected to expansion board
through these four connectors.
CON1 Connector
CON1 is one of 80-pins connector which is used to connect +5V power signals
and FPGA IO signals between core board and expansion board. Please note that
the voltage level of IO from FPGA bank34 is +1.5V standard. Table 2-10-1 list
the pin assignment of CON1conector.
