The is a robust design, but it suffers from "legacy syndrome." The schematic shows a mix of through-hole connectors (for reliability) and tiny 0402 resistors (for modern density). If you are cloning this or repairing it, pay special attention to the Enable sequencing . Without the 3.3V rail coming up 2ms after the 5V rail, the LVDS transmitter refuses to lock. d10240p1a schematic work
