Introduction to SN65HVD485EDGKR

The SN65HVD485EDGKR from Texas Instruments is an integrated half-duplex EIA-485 transceiver designed for applications that require high-levels of noise immunity, wide common-mode voltage range, high slew rate, and low count of parts. It is usually used as an alternative toRS485 transceivers and features low operating power, low levels of dissipation, low electromagnetic radiation levels, and high levels of noise rejection in a compact package.

Applications

This transceiver is widely used in industrial automation, energy storage systems, and general-purpose data communication applications. It can also be used in data transmission systems that use both unidirectional and bidirectional data, such as programmable logic controllers, remote terminal sales, isolated analog measurement systems, and distributed control networks. It can also be used in systems that simultaneously support a mix of communication baud rates, as well as applications that require efficient communication between two separate circuits.

Working Principle

The SN65HVD485EDGKR transceiver operates on a basic differential data transmission system. This system consists of two pairs of wires – the transmit pair, and the receive pair. Data is sent along the transmit pair, and the receiving device is connected to the receive pair. The transceiver is designed to measure the voltage differential between the wires, and convert that voltage into a logical 0 or 1 digital signal.The transceiver is also responsible for distinguishing between a signal sent on the transmit pair, and noise caused by other devices in the environment. This is accomplished by measuring the signal-to-noise ratio of the signal on the input. If the signal-to-noise ratio is below a specified threshold, the signal is disregarded and the data is not sent. The signal is then sent to the receiver via the communication bus, where it is checked for any errors before being processed by the receiving device. The signal-to-noise ratio of the signal decreases as it travels through the communication bus, so the signal must be amplified before being received by the receiving device. This amplification is done by the SN65HVD485EDGKR transceiver.

Conclusion

The SN65HVD485EDGKR is an integrated half-duplex EIA-485 transceiver designed for applications that require high levels of noise immunity, wide common-mode voltage range, high slew rate, and low count of parts. It is most commonly used in industrial automation, energy storage systems, and general-purpose data communication applications. The transceiver operates on a basic differential data transmission system and is responsible for detecting and amplifying signals, as well as distinguishing between a signal sent on the transmit pair and noise caused by other devices in the environment. This ensures a reliable and robust data transmission system.
