Working Principles

The SN65LVDS105DG4 operates by converting parallel data into serial data using LVDS technology. It accepts CMOS/TTL level inputs and converts them into differential LVDS signals, which are then transmitted over a twisted-pair cable. On the receiving end, it receives the differential LVDS signals and converts them back into parallel data.

The LVDS technology used in this IC provides high-speed data transmission with low power consumption. It achieves this by transmitting data differentially, where the voltage difference between the positive and negative lines represents the data. This differential signaling allows for better noise immunity and reduces electromagnetic interference.

Application Field Plans

The SN65LVDS105DG4 is commonly used in various applications that require high-speed data transmission over long distances while maintaining low power consumption. Some of the typical application fields include:

1. Display Technology: Used in LCD monitors, TVs, and projectors to transmit video data from the controller board to the display panel.
2. Industrial Automation: Employed in industrial control systems to transmit sensor data and control signals between different modules.
3. Automotive Electronics: Utilized in automotive infotainment systems, instrument clusters, and advanced driver-assistance systems (ADAS) for reliable data communication.
4. Communication Systems: Integrated into networking equipment, such as routers and switches, to transmit data between different network nodes.
