Description:
The ZH-CR75-8 is a full-color LED display receiving card, a core control component used inside LED video wall cabinets to receive, process, and distribute video/image data to the LED modules that make up the display. It works alongside a corresponding sending card (installed in a control PC or video processor) to form a complete LED display control system, translating incoming video signals into the precise pixel-level output required to drive the LED matrix in real time.
At the heart of the board is an Altera Cyclone IV FPGA (EP4CE6F17C8N), which provides the processing power needed to handle real-time video data distribution, pixel mapping, and display timing with low latency — critical for smooth, flicker-free LED video playback. The board also includes a Winbond serial flash memory chip (W9864G2IH-5 series) for firmware and configuration storage, along with an SGM4800 series component supporting the board's power and signal management functions.
The card features eight HUB75-style IDC ribbon cable output ports (organized in JP1–JP8 connector groups), allowing it to drive multiple LED module chains directly from a single card — a hallmark of "wide" or high-port-count receiving cards designed for larger or more complex LED cabinet configurations. It also includes an RJ45 Ethernet-style port for receiving incoming video data from the sending card or network-based control system, and a set of screw-terminal power inputs for connecting the board to the LED display's DC power supply.
This type of receiving card is typically installed inside LED display cabinets (indoor or outdoor video walls, advertising screens, stage backdrops, and similar large-format LED installations) and is responsible for ensuring accurate, synchronized image reproduction across the entire display surface.
