Functions and applications of LVDS cable assemblies
I. Functional characteristics
‌Differential signal transmission‌
Adopting a low voltage (about 350mV) differential pair structure, data is transmitted through two lines with opposite polarities, effectively suppressing common mode noise and electromagnetic interference, and improving signal integrity.

‌Low power consumption and low electromagnetic radiation‌
The constant current source drive mode (typical current 3.5mA) combined with CMOS technology significantly reduces static power consumption (about 1.225mW), and the electromagnetic radiation intensity is only 1/10 of that of traditional TTL/CMOS.

Here’s a more detailed look at the functions and applications:
Functions:
High-Speed Data Transmission:
LVDS cables excel at transferring large amounts of data quickly, crucial for applications like high-resolution displays and real-time video feeds.
Low Power Consumption:
LVDS technology is designed to minimize power draw, making it suitable for battery-powered devices and applications where power efficiency is critical.
Long Cable Lengths:
LVDS can transmit data over longer distances compared to some other technologies, enabling wider placement of components in various systems.
Noise Immunity:
The differential signaling in LVDS helps to reduce noise interference, ensuring reliable data transfer even in noisy environments.
Organization and Efficiency:
Cable assemblies help organize multiple wires into a single, manageable package, reducing the risk of tangled wires.
Protection:
Assemblies protect wires from environmental factors such as moisture, heat, abrasion, and chemicals.

‌High-speed data transmission capability‌
The theoretical limit rate is 1.923Gbps, supporting high-speed interface requirements such as HDMI and DisplayPort, and is widely used in video streaming, automotive ADAS and other scenarios.

‌Strong environmental adaptability‌
Supports a wide temperature range (-40℃～125℃), is vibration-resistant and corrosion-resistant, and meets the connection requirements of harsh working conditions such as automotive electronics and industrial equipment.

‌Flexible termination design‌
The receiving end achieves impedance matching through a 100Ω parallel resistor, which simplifies system design and enhances timing accuracy, and is suitable for backplane communication and long-distance transmission.
