LVDS - J26[edit | edit source]
J26 is a vertical double row straight 20-pin 1.25mm pitch header. This interface shows how to implement a differential connection to an LCD screen. As known, Zynq does not implement an LCD controller, however this can be integrated in FPGA fabric as shown by this example: https://wiki.analog.com/resources/tools-software/linux-drivers/platforms/zynq. The following table reports the pinout of the connector:
