The ST1480ABDR is a medium-to-low-speed, dual-interface transceiver that provides robust and reliable single-ended signaling using differential signals, with a selectable bit rate of up to 25 Mbps. It can be used in applications such as automotive, industrial and military where ruggedness and reliability are important. This article will discuss the application field and working principle of the ST1480ABDR.

Application Field

The ST1480ABDR is applicable to a wide variety of applications, from automotive to industrial and military, making it a versatile transceiver. In the automotive sector, it can be used in systems such as CAN (Controller Area Network), LIN (Local Interconnect Network) and K-Bus protocols. In industrial applications, the ST1480ABDR can be used to control RS-485 / 422 processes, as well as industrial field buses. It has also been used in ultra-rugged military applications, where it is required to handle extreme conditions with precision and reliability.

Working Principle

The ST1480ABDR utilizes differential signaling to reduce the effects of noise on the data signal. This type of signaling allows for a high degree of noise rejection and improved performance. The transceiver has the ability to detect and reject certain types of noise, increasing immunity to interference and allowing for robust and reliable operation. The transceiver can be configured for either a single-ended or differential interface for greater flexibility.

The transceiver operates using a low-speed differential-voltage signaling technique which eliminates the need for a ground reference. The input signals are typically single-ended and the high termination voltage will protect the device from over-voltage or reverse-voltage conditions. The driver outputs are differential and can be configured to operate at different rates, depending on the specific application. The transceiver contains ESD protection up to 11 kV. The ST1480ABDR also has selectable polarity and direction, allowing the user to adjust the direction and terminate the line, depending on the application.

The transceiver is also designed to detect bus abnormalities, such as short circuits, open circuits, transients and ESD events. These events can be detected and the transmission of data can cease until proper working conditions are restored. This provides an extra layer of protection and makes the transceiver robust in harsh environments.

The ST1480ABDR is a versatile transceiver that can be used in a variety of applications, from automotive to industrial and military. Its robustness and flexibility make it a great choice for those looking for a reliable and rugged signaling solution.
