RF Evaluation and Development Kits, Boards are special tools for evaluation, debugging, development and integration of RF circuits and systems. They provide a convenient platform for users to understand their performance, and are used during the design and manufacturing of electronic products in RF applications. Among the products in this category, TSW40RF82EVM (Texas Instruments Steering Wheel) is a popular choice. This article focuses on the application field and working principle of TSW40RF82EVM.

Application Field

The TSW40RF82EVM consists of a control processor, an RF transceiver, an analog-to-digital (A/D) converter, digital signal processing (DSP) functions and a two-step power detector. The steering electronics can communicate with an external environment using serial communication interfaces, e.g. SPI, CAN, UART, USB, etc. and embedded memory, e.g. RAM, ROM, FLASH and EEPROM. With its wide range of features, the TSW40RF82EVM is designed for use in the automotive sector for applications such as control systems, power management, wiring management, and in-car communication.

The TSW40RF82EVM also has the capability to connect to an external device and become part of an extended system. This allows for the integration of external sensors with digital readouts, as well as digital control systems, for a wide range of automotive applications. For example, the TSW40RF82EVM can be used in automotive applications such as ABS, automotive body control, vehicle to vehicle communication, telematics and adaptive cruise control.

Working Principle

The TSW40RF82EVM works on the principle of frequency hopping. Frequency hopping is a way of encoding a radio transmission signal by rapidly switching the carrier frequency among multiple pre-determined frequency channels (or “hops”). As the receiver follows the same predetermined sequence of hopping frequencies, the signal can be maintained at a substantial power level yet remain secure from eavesdroppers. This enables faster and more accurate transmission and reception.

The TSW40RF82EVM uses automated frequency hopping spread spectrum (FHSS) to provide secure and reliable radio frequency transmission. This system is capable of hopping from one frequency band to another at any predetermined time interval. During transmission, the TSW40RF82EVM continuously evaluates the RF link performance, taking into consideration the effects of interference and other environmental factors. The TSW40RF82EVM can also adjust its hopping pattern according to the input signal. This ensures the highest possible transmission quality and reliability.

The TSW40RF82EVM is a multifunctional RF steering wheel designed for automotive applications. It features automated frequency hopping spread spectrum technology that enables secure and reliable radio frequency transmission. The TSW40RF82EVM works by rapidly switching the carrier frequency to multiple predetermined frequencies, allowing faster and more accurate transmission and reception. This makes it an ideal product for automotive control systems, power management, wiring management, and in-car communication.
