Introduction

SN65HVD3086EDGSG4 is a differential driver and receiver device from Texas Instruments. It is a part of the high-speed transmission Networking (HSTN) family of products that offer a strong signal-transmission for those who need to transfer data over long distances without signal degradation. This device is extremely useful in circuit designs that require bi-directional communication between two points in the form of serial data streams. This article will cover the application field, working principle and features of the SN65HVD3086EDGSG4.

Application Field

The SN65HVD3086EDGSG4 is designed for signals that are sensitive to degradation, such as those found in computer networks, automotive systems, and medical instrumentation. It is designed for RS-485/422 systems and is capable of transferring up to 256kbit/s of data. The device also supports high-speed data transfer over a telephone line using the built-in V.22bis modem capabilities.The device is especially well-suited for point-to-point or multi-point systems needing bi-directional communication. It can be integrated into existing systems utilizing RS-232, RS-4…82, and RS-4…826 interfaces. The device is fully compatible with the commonly used TTL, Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Modular Encryption Algorithm (MEA) standards and operates with a power supply voltage range between 3.2V and 5.5V.

Working Principle

The SN65HVD3086EDGSG4 is a differential driver and receiver device that uses communication technologies such as full-duplex, half-duplex and single-wire communications. This device uses differential signaling which enables it to transmit data over a twisted-pair cable configuration. The two differentials pairs (A and B) are used to transmit and receive data from the two receivers on the board. The device has three transceivers and two receivers – one for each differential pair. The transceivers convert the data from TTL, AES, DES or MEA into a serial format for transmission over the cable. When transmitting data, it first enters the transmitter, where it is converted into a differential signal. It is then sent across the two differential pairs which balance the signals, reducing EM interference. At the receiving end, the signals are converted into their original form. The device is also capable of Auto Send and Auto Receive functionality. This allows the device to intelligently sense incoming transmissions and automatically initiate a transfer or acknowledge the received information.

Features

The main features of the SN65HVD3086EDGSG4 are as follows:• High data rate – up to 256 kilobits per second• Full-duplex, half-duplex and single-wire communication• Automatic directional sensing• Able to support RS-485/422 protocols• Built-in modem capabilities, compatible with the V.22bis standard• Built-in AES, DES and MEA encryption support• Operating voltage of 3.2 volts (V) to 5.5 volts (V)• Low power consumption• RoHS Compliant

Conclusion

The SN65HVD3086EDGSG4 is an ideal solution for those requiring bi-directional communication between two points over long distances and with no signal degradation. It is extremely versatile with its ability to support a wide range of protocols and encryption standards, and is also capable of sustaining high data rates with low power consumption. Its auto-sensing functionality makes the device even easier to integrate into existing systems and further adds to its overall utility.
