Introduction

TRS207CDW is a high-performance, low power receiver/transmitter (R/T) module for applications in the automotive environment. The TRS207CDW has been designed to suit the demanding conditions of automotive systems. It provides a cost-effective way to meet the rigorous automotive requirements for flexibility, functionality and reliability.

Application Field

TRS207CDW is a versatile interface device, generally used in automotive systems such as vehicle-to-vehicle communications, remote control transmission, and vehicle-to-infrastructure communications. It is a half-function module, utilizing only a fraction of its high-speed differential line drivers to transmit and receive data. The TRS207CDW is ideal for protocols requiring high-speed communication, such as CAN (Controller Area Network) and LIN (Local Interconnect Network).

The module can also be used in the automotive aftermarket, providing an excellent solution for the programming, diagnostics and monitoring of onboard diagnostic (OBD) systems. The TRS207CDW is ideal for automotive applications that require data transfer between a microcontroller, a gateway or an in-vehicle network.

Working Principle

The TRS207CDW module is equipped with low-power drivers, receivers and transceivers that can operate in three different protocols. It uses the digital logic and isolation techniques provided by the LIN (Local Interconnect Network) protocol for communication between the LIN master and satellite nodes. It also supports the Controller Area Network (CAN) protocol that is used in a variety of in-vehicle systems, providing an efficient, reliable communication between nodes.

In addition, TRS207CDW also supports the High Speed Serial (HSS) protocol, which uses two differential drivers and two receivers to provide high-speed data communication between two nodes. This protocol is suitable for applications where large amounts of data need to be transferred at high speed between two nodes.

The TRS207CDW module integrates selective logic functions, such as level-independent repeaters, line/splitting transceivers, and differential line drivers. This allows it to increase the signal integrity and transmission speed of the communication links between the nodes in automotive systems.

The module is also able to support the multi-cast signal transmission and reception, which is a power-saving technique typically used in CAN communications. This feature allows data to be transmitted simultaneously to multiple receivers, thus minimizing power consumption of the system.

With its flexible architecture, the TRS207CDW can be used in a wide range of automotive applications. It offers good immunity to electromagnetic interference, meaning that it can withstand high-voltage/high-current surges in the system, even when exposed to extreme environments.

Conclusion

As a highly integrated system-on-chip receiver/transmitter module, the TRS207CDW offers a cost-effective solution for automotive applications. The module provides reliable communication links between two or multiple nodes, utilizing various communication protocols such as LIN, CAN, and HSS. In addition, its flexible architecture makes it suitable for a variety of in-vehicle applications.
