SN65LVDS389DBTR is a driver, receiver, and transceiver for low-voltage differential signaling (LVDS), which provides the appropriate voltage to drive and receive TTL/CMOS data-level compatibility and differential signaling during a transmission. The device is designed for applications that require low power and wide data throughput speeds. It combines low-power operation and extremely low-voltage differential signaling to reduce power consumption while reducing cross-talk, noise, and ground bounce.

The SN65LVDS389DBTR device can be used in applications that require maximum signaling rates in excess of 400 Mbps and distance of up to 15 meters, such as flat-panel display data transmission, DVD players, digital cameras, and routers. It is also a suitable replacement for the low-cost and line-powered applications that require LVDS signaling for networking, communications, and imaging.

The SN65LVDS389DBTR driver and receiver are specifically designed to provide high performance and wide common-mode voltage range performance. It is capable of providing an output voltage range from 0.4 V to 1.4 V for the driver, and a 0.4 V to 3.0 V for the receiver. It is also optimized for low power dissipation, with a typical quiescent current of 0.6 mA for the driver and 0.8 mA for the receiver. The wide common-mode voltage range is particularly advantageous in networking and other applications that require a lower input voltage swing while still providing robust data communication.

The working principle of the SN65LVDS389DBTR device is a bit-serial transmission of data on two opposite (differential) lines. The data is sent in NRZ (Non Return to Zero) format, meaning the data is transmitted one bit at a time. The two lines are clocked by a separate clock signal. When a bit is sent over the lines, the clock sends a pulse in order to synchronise the sending of the next bit. This clock is not part of the data signal, which makes the signal more reliable and also reduces the amount of power dissipation.

The SN65LVDS389DBTR driver is used to send the data and the receiver is used to receive the signal. The driver monitors the transmitted data and adapts the output level depending on the logical state of the data. The receiver is designed to provide low noise, low power operation and wide common-mode voltage range. It is optimized to receive the transmitted data with minimum jitter. The receiver detects the logical states of the differential data and passes them to the output.

The SN65LVDS389DBTR device is ideal for applications such as video transmission, automotive infotainment, voice and video conferencing, HDTV, and other high-speed data applications. Additionally, it is also suitable for applications that require low power and wide data throughput speeds. It is specifically designed for maximum performance and wide common-mode voltage range performance, making it an ideal device for networking, communications, and imaging applications.
