Overview of the SN65LVDS4EVM

The SN65LVDS4EVM is an evaluation and demonstration board from Texas Instruments which contains one SN65LVDS4 driver and one SN65LVDS4 receiver. The board is designed to allow users to easily evaluate and test the performance of LVDS/VIS interfaces. The board contains all the necessary components to quickly set up and prototype a system utilizing LVDS/VIS technology.

The SN65LVDS4 driver/receiver offers an optimal combination of high speed, low power and low voltage differential signaling (LVDS) compatible outputs. The device can be used as either a transmitter or a receiver, making it suitable for various applications. The board also features test wire loops to facilitate testing of bidirectional signaling on the board as well as a voltage controlled termination network that can be used to optimize signal integrity.

Application Field and Capabilities of the SN65LVDS4EVM

The SN65LVDS4EVM is well-suited for a range of LVDS/VIS applications including transmitting and receiving data, as well as testing signal integrity. The board also has the capability to control termination resistance for optimizing signal integrity in bidirectional communication applications. This is useful in applications that require high speed data transfer between devices over a short distance.

Additionally, the board can be used to prototype applications such as low latency video or audio applications, video display panels, portable and compact system integration, redundant system architectures, point to point automation systems, and embedded industrial control systems. Also, the use of LVDS/VIS signals on board ensures compatibility with products such as laptop computers, cell phones, cable modems, set-top boxes, and HDTVs.

Working Principle of the SN65LVDS4EVM

The SN65LVDS4EVM uses low voltage differential signaling (LVDS) for data transfer between the transmitter and receiver. The transmitter takes in TTL level signals and converts it into a high speed differential signal, and the receiver takes in the differential signal and converts it back into TTL signals. The board uses a variable impedance mechanism to optimize signal integrity in bidirectional communication applications. This mechanism makes use of adjustable on-board resistors that are used to create an impedance matched termination which prevents reflections on the signal when data is transmitted in both directions.

When connected to external devices, it is important to understand the LVDS/VIS impedance convention. This defines how the signal should be terminated on each end. The board includes a pre-programmed termination impedance that can be used to automatically adjust the termination impedance for any application.

In addition to the LVDS/VIS feature, the SN65LVDS4EVM board also provides a test wire loop that allows users to test bidirectional communication. The test wire loop enables a two-way communication algorithm to determine whether or not the data packets are being received correctly. The board also includes indicators that can be used to monitor the status of the board.

In summary, the SN65LVDS4EVM evaluation and demonstration board from Texas Instruments is an ideal building block for testing, prototyping, and troubleshooting low voltage differential signaling (LVDS) and variable impedance signaling (VIS) applications. The board features adjustable termination networks, test wire loops, and indicators, making it an invaluable tool in the development process.
