Working Principles

SN65LVDS390PWG4 operates based on the principles of LVDS technology. It uses differential signaling, where data is transmitted as the voltage difference between two complementary signals (positive and negative). This differential approach provides noise immunity and allows for high-speed data transmission.

The transmitter section of the device converts parallel data into LVDS signals, while the receiver section converts the received LVDS signals back into parallel data. The receiver also incorporates equalization techniques to compensate for signal degradation caused by transmission line losses.
