SN65EL16DGK is a driver, receiver, and transceiver designed by Texas Instruments. This device interfaces and drives LVDS (Low-Voltage Differential Signaling) data lines over a differential pair of transmission lines in a low-cost, low-power application. SN65EL16DGK is targeted for reducing EMI (electromagnetic interference) from LVDS signal lines in a board-to-board interconnection system. It provides an optimal signal performance for data rates up to 250 Mbps and signal transmission up to 100 meters and higher depending on the cable type.

SN65EL16DGK driver and receiver functionality is divided into a driver side-channel and a receiver side-channel. The driver side-channel interfaces and transmits LVDS input data over a differential pair of transmission lines whereas the receiver side-channel receives the incoming LVDS data, compares it against a reference voltage, and outputs the data as logic-levels. The system thereby eliminates need for external line termination. To optimize the logic level margins, both the driver and the receiver operate with a common reference voltage.

SN65EL16DGK provide a better signal-to-noise density than AC-coupled LVDS busses. This results in shorter propagation delay and a smaller error rate due to transmission line noise. The device also provides an internal line input termination and an on-chip reference voltage generation, so that the output is compatible with other logic families regardless of the variation in supply voltage and temperature.

SN65EL16DGK has a higher data rate capability than conventional standard LVDS, allowing for a higher performance in data transmission systems. It’s compatible with 3.3V and 5V logic families and can support compatibility with two types of physical media - twisted-pair busses and ribbon cables. The device sends and receives data over a differential pair of lines, in which each line carries the opposite logic level of the other, thereby eliminating any electrical interaction.

SN65EL16DGK is particularly suitable for applications where small size, low power consumption, and high noise immunity are needed. This could include automotive applications for CANbus, MOST, E-bus, and audio-video applications, as well as applications related to avionics, industrial, military and medical systems. As such, due to its low-cost and low-power consumption, SN65EL16DGK is one of the most popular LVDS solutions for applications in low-cost and low-noise environments.

In summary, SN65EL16DGK is a reliable, low-cost, low-power driver, receiver, and transceiver designed for low-noise LVDS applications. It allows for high data-rate signals up to 250 Mbps, while its small size and low power consumption make it suitable for many applications in the automotive, avionics, industrial, military, and medical systems.
