The part number **47LV-3D0YR-R** refers to a high-performance **LVDS (Low-Voltage Differential Signaling) 2-Differential Channel 1:2 De-Multiplexer / Multiplexer Switch**. It is primarily used in high-speed digital video applications, such as television motherboards and display interfaces. --- ### 1. Key Technical Specifications Below are the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Function** | 2-Differential Channel 1:2 Mux/DeMux | | **Signal Type** | LVDS / DisplayPort / HDMI | | **Bandwidth** | ~2.0 Gbps per channel | | **Supply Voltage (Vcc)** | 3.3V (Typical) | | **Low Power Consumption** | Active: < 10mW / Standby: < 10µA | | **ESD Protection** | Up to 8kV (HBM) | | **Package Type** | 42-Pin TQFN or similar small footprint | --- ### 2. Functional Description The device acts as a high-speed "traffic controller" for digital signals. It allows a single source (like a System on Chip - SoC) to switch between two different outputs (like two different LCD panels) or vice versa. #### Core Features: * **Bidirectional Operation:** Can function as both a Multiplexer (2 inputs to 1 output) and a De-multiplexer (1 input to 2 outputs). * **Low Crosstalk:** Designed to minimize interference between adjacent high-speed signal lines. * **High Impedance Mode:** When the device is disabled, the outputs go into a high-impedance state to prevent loading the bus. --- ### 3. Common Applications This part is commonly found in consumer electronics that handle high-definition video data: 1. **Smart TVs:** Switching between internal processing units and different display panel interfaces. 2. **Laptops/Tablets:** Routing LVDS or eDP (embedded DisplayPort) signals from the GPU to the internal screen or an external docking station. 3. **Digital Signage:** Distributing a single video feed to multiple display modules. 4. **Automotive Infotainment:** Handling video data for dashboard clusters and head units. --- ### 4.
