Hi I'm trying to transmit digital signals through a cable. In orther to avoid noise, I am using a differential output (LVDS) to transmit the information from the FPGA to a Cable. At the end of the cable, I'm using a converter to convert the differential signal to a single-end signal (LVDS to Single End converter). For that I need to feed my converter circuit through pin 6 of pmod connector (pin6 = vcc pin = 3.3V). Initially everything was working properly. However the other day, I switched on the board again (Atlys Board) and checked that I no longer have vcc on pin 6 (pin6 = vcc pin = 0V). Can anyone explain what's going on? Is the board damaged?
