TUSB214IRWBR

Overview

TUSB214IRWBR is an advanced, special-purpose interface designed to enable more efficient communication between an analog system and a digital system. This interface offers many advantages over conventional, single-ended architectures, such as galvanic isolation, increased reliability, and decreased EMI/RFI emissions. Additionally, TUSB214IRWBR is optimized for industrial and automotive control applications that require bidirectional behavior.

Application Field

TUSB214IRWBR interfaces can be found in many industrial and automotive applications, such as powertrain and engine control, HVAC systems, infotainment systems, and motion control applications. It is especially useful in high speed serial, bidirectional systems that require improved signal integrity, noise immunity, and high data rates.

Working Principle

The TUSB214IRWBR is a two-wire, half-duplex interface, meaning it has two wires for communication and can only transmit or receive information at a given time, not both. This interface operates on differential signaling, meaning it sends two complementary signals of opposite polarity and monitors for changes in a current or voltage. This technique provides immunity to electrical noise, high reliability and low EMI/RFI.

The interface uses a synchronous clock signal to enable two-way communication, and data is encoded using the Manchester II code. The receiver utilizes a recovery algorithm to recover the clock signal from the data stream and then computes the encoding. This encoding technique helps ensure that data is sent in a timely, reliable manner, and that the receiving system can accurately interpret the data.

The TUSB214IRWBR interface is capable of data rates up to 10 Kbps and has a maximum working voltage of 5.5V. The interface is also very resistant to interference and has a robust design that allows it to operate in harsh environments.

Conclusion

The TUSB214IRWBR interface is designed to enable more efficient communication between an analog system and a digital system. This interface has many advantages over conventional, single-ended architectures, such as galvanic isolation, increased reliability, and decreased EMI/RFI emissions. Additionally, the TUSB214IRWBR is optimized for industrial and automotive control applications that require bidirectional behavior, and is capable of data rates up to 10 Kbps, with a maximum working voltage of 5.5V.
