What is LVDS and how does it work?
LVDS (Low-Voltage Differential Signaling) is a high-speed digital signaling technology used for transmitting data over short to medium distances. It works by transmitting data as a differential signal, which means that the data is transmitted as a pair of complementary signals, one being the inverse of the other. This allows for a high degree of noise immunity and enables the transmission of high-speed data with minimal degradation. The differential signaling approach also helps to reduce electromagnetic interference (EMI) and radio-frequency interference (RFI), making it an ideal choice for applications where data integrity is critical.
The LVDS technology uses a low-voltage swing, typically in the range of 350 mV, to minimize power consumption and reduce EMI. The differential signals are transmitted over a pair of wires, and the receiver detects the difference between the two signals to determine the original data. This approach enables the transmission of high-speed data, typically up to 1.5 Gbps, over distances of up to several meters. LVDS is widely used in a variety of applications, including display interfaces, high-speed data acquisition systems, and industrial control systems, where high-speed data transmission and low power consumption are essential.
