Introduction

The SP3483EN-L/TR is a highly reliable, flexible, low power and intuitive device for high data rate communication link applications. It is a 3.3V CMOS transceiver belonging to the 32-level interface family. The SP3483EN-L/TR is an interface device that can meet any need for high-speed, low cost, low power consumption and medium to long-distance communication solutions making it an ideal component for many system designs.

Application Fields

The SP3483EN-L/TR is useful in a variety of applications varying from communication systems to data acquisition systems as well as instrumentation, test and measurement systems. Due to its small size and low power consumption, it is particularly suited to applications that require high performance results in these fields with limited physical space and power constraints.Applications in communications systems include, but are not limited to: modems, multiplexers, Framers, High-speed Digital Subscriber Lines (xDSL), industrial Ethernet networks, VDSL (high-speed data over telephone lines) and powerline networks, audio video systems and CAN bus networks based on CAN protocol. In addition, applications in data acquisition systems include, but are not limited to: short distance data acquisition, wireless data acquisition technologies and multi-level data acquisition.

Working Principle

The SP3483EN-L/TR, as a CMOS transceiver, is intended to be driven by a dc voltage source or transformer coupled source, allowing it to offer a wide range of input voltage ranges, down to 2.5 V, that adapts to most communication protocol standards. The device is typically coupled to the driver side of the communication link, with the driver output and the CMOS transceiver representing the “line” side of the link. The SP3483EN-L/TR offers two levels of error recovery, making it ideal for applications where reliability is critical, such as critical communication systems or instrumentation applications. The device incorporates a differential transmitter that converts TTL logic levels into an RS-232 compatible signal, and a differential receiver that converts RS-232 signals into TTL logic levels. The device also includes a gap detection feature for detecting communication link breaks or disconnects, and can switch to the receive side of the link automatically upon detection of such events. The device also incorporates a synchronization error detection feature that monitors any incoming signal on the serial data line in order to detect any errors. It can detect unacceptable signal levels, errors in data rate and errors in signal formats, offering advanced error detection and easy debugging.

Conclusion

The SP3483EN-L/TR is a low power, high performance CMOS transceiver for a variety of communication applications. It offers reliable performance and advanced error reporting features, making it ideal for systems that require high performance, reliability, and advanced feature sets. The device is suitable for any system that operates over short to medium distances, and can be used in a wide variety of applications, from modems and multiplexers to industrial Ethernet networks, VDSL and powerline networks.
