Working Principles

The SN75LVDS84DGGR is a LVDS Serializer/Deserializer IC that converts parallel data from a microcontroller or other digital source into serial data using LVDS technology. It can also convert serial data back into parallel form. LVDS technology uses differential signaling, where data is transmitted as the voltage difference between two lines (positive and negative). This allows for high-speed data transmission with low power consumption and noise immunity.

Detailed Application Field Plans

The SN75LVDS84DGGR is commonly used in various applications such as:

1. Display Systems: Used in LCD monitors, TVs, and projectors for transmitting video data from the controller to the display panel.
2. Communication Systems: Used in high-speed data communication interfaces, such as Ethernet switches and routers, to transmit data between different network devices.
3. Industrial Automation: Used in industrial control systems for transmitting sensor data and control signals over long distances with high noise immunity.
4. Automotive Electronics: Used in automotive infotainment systems, instrument clusters, and driver assistance systems for reliable data transmission in harsh environments.

Detailed and Complete Alternative Models

1. SN65LVDS84: Similar to SN75LVDS84DGGR, but with a wider supply voltage range of 2.5V to 3.6V.
2. DS90LV048A: LVDS Serializer/Deserializer IC with 8 channels and a data rate of up to 400 Mbps.
