LVDS is the low-voltage differential signal. The core of this technology is the high-speed differential transmission of data with very low voltage swing. It has the characteristics of low power consumption, low bit error rate, low crosstalk and low radiation. Its transmission medium can be copper PCB connection or balanced cable. LVDS is more and more widely used in systems that require high signal integrity, low jitter and common mode characteristics.

Application mode
1. One way point-to-point
This is a typical application mode. Each point-to-point differential pair consists of a driver, interconnector and receiver. The driver and receiver mainly complete the conversion between TTL signal and LVDS signal. The interconnector consists of a cable, a differential conductor pair on a PCB, and a matching resistor. Unidirectional point-to-point application mode is an ideal interface for communication among chips, plug-ins and racks.
2. Bidirectional point-to-point
It can realize bidirectional half duplex communication through a pair of twisted pair wires. It can be composed of standard LVDS driver and receiver. But the better way is to use bus LVDS driver, that is, blvds, which is designed to connect loads at both ends of the bus.
