Evaluation and Demonstration Boards and Kits provide a range of different solutions for evaluating, testing, and demonstrating electronic components and assemblies. The TXS4558EVM (Evaluation Module) is a versatile development platform designed for the evaluation and performance verification of Texas Instruments\' TMS4558 IC, a 4-channel Smart Audio Processor. Based on the TMS4558 IC, the TXS4558EVM offers a wide range of features including a powerful on-board audio processor, a digital signal processor (DSP) and a host of audio connectors for use in product development, circuit design, and application development.

Application Field

The TXS4558EVM provides a powerful audio development platform for the evaluation of sound fidelity and audio performance. The module is especially suitable for audio engineers, product developers and engineers working on audio projects or product development, as well as students studying audio engineering. The TXS4558EVM can be used for a wide range of applications that require high-quality audio processing such as recording studios, audio broadcasting, staging, cinema and home theatre systems, and music playback systems.

Working Principle

The working principle of the TXS4558EVM is based on the TMS4558 IC. The base processor is a 32-bit ARM Cortex-M4 processor incorporating the TMS4558 IC with four dual channel input/output ports, a digital signal processor (DSP) and host of audio connectors. The four dual-channel input/output ports are capable of connecting up to eight microphones or four stereo microphone pairs per port. The DSP contains a 32-bit core that handles all the signal processing for the onboard audio processor, allowing for audio algorithms such as echo cancellation, de-noising, equalization, and room simulation.

The TXS4558EVM also comprises an eggshell-based audio reference design, including amplifier/power stages, connections to the audio processor and microphone elements, and a power supply module. The reference design enables the user to quickly and easily configure the audio performance of the module using advanced controls such as crossover frequency, input/output gain, and signal routing. The reference design also provides the user with an intuitive graphical user interface (GUI) for controlling and monitoring the audio output and performance on the module.

In addition to the audio performance verification, the TXS4558EVM also provides the user with access to the debugging and programming ports which enable the user to program and debug their applications. The debugging ports also connect the user to a development system and offer tools for creating custom audio applications.

The TXS4558EVM is a powerful and versatile audio development platform that provides the user with a wide range of features and capabilities for evaluating and verifying audio performance. The module is especially suitable for audio engineers, product developers and engineers working on audio projects or product development, as well as students studying audio engineering.
