Low Voltage Differential Signaling (LVDS) is a standard electrical signaling scheme used for high-speed data transmission over relatively short distances. It is commonly used to transmit digital data between various components in electronic devices, such as computers, displays, and communication systems.
LVDS operates by employing a pair of conducting wires to transmit data in a differential manner. Instead of using a single wire to carry the electrical signal, LVDS uses two wires with opposite polarities. This differential signaling method helps to reduce electromagnetic interference (EMI) and noise, and improves signal integrity.
The voltage levels in LVDS are relatively low, typically around 350 millivolts. The positive and negative voltages represent logical values, such as 0 and 1. This low voltage level allows for high-speed data transmission without consuming excessive power.
LVDS is known for its high data transfer rates, often reaching several gigabits per second. It offers significant advantages in terms of low power consumption, high noise immunity, and good signal integrity. It is also utilized in several industry standards, including DisplayPort, FPD-Link, and Serial ATA (SATA).
Due to its advantages, LVDS is commonly used in applications that require high-speed data transmission and low power consumption, such as high-resolution displays, multimedia systems, and high-speed communication links.
