SP3491CN-L Application Field and Working Principle

The SP3491CN-L is a driver, receiver and transceiver interface specifically designed for driving multi-channel applications and providing high channel isolation and noise suppression. This interface is a versatile integrated chip from Exar Corporation, and is ideal for high speed, high power and low voltage serialization applications. Its features include low power consumption and wide input voltage range.

Application Field

The integrated chip has been designed for applications facing the transmission of long distances through cable or fiber and is also ideal for use in serializing multiple channels as well as providing high channel isolation and noise suppression. It is used in various applications ranging from industrial process control to data acquisition systems, as well as in various communication applications. Such applications include:

• High-speed instrumentation and control
• Video and audio broadcasting
• Medical imaging systems
• Telecommunication system networks
• Secure WiFi communication
• Distributed Automation Systems

Working Principle

The SP3491CN-L from Exar is suitable for all sorts of serialization applications due to its on-chip features including driver, receiver and transceiver functions, as well as its variable configurability options, adjustable slew rate, trigger delay and receiver hysteresis. In addition, it also contains low power consumption, wake-up input and adjustable voltage outputs.

The interface is designed using the dual line approach, which helps it facilitate faster transmission and reduce noise generation. The output signal is formed by connecting two separate complementary lines, a positive line and a negative line, resulting in a stronger signal and improved noise immunity. Additionally, the driver also contains a reference voltage generator, which further helps it produce better signal clarity.

The receiver works by comparing the incoming signal’s amplitude to a fixed threshold. If the signal’s amplitude falls below the threshold, the receiver sends an acknowledgement signal indicating that the signal was received. The transceiver, on the other hand, has the capability to transmit and receive both synchronous and asynchronous data.

In order to ensure compatibility across different electronic platforms, the SP3491CN-L is designed to support a wide range of input and output voltage levels. This makes it suitable for applications that require an adjustment of the interface’s characteristics depending on the specific requirements of the application.

Conclusion

The SP3491CN-L from Exar is a driver, receiver and transceiver interface designed to transmit data over long distances and provide a high degree of channel isolation and noise suppression. Its dual line approach helps reduce noise generation, while its adjustable slew rate, trigger delay, and receiver hysteresis allows it to be used in a variety of applications. Its wide input and output voltage range also ensures compatibility with a wide range of platforms.
