Audio Processor 64-Pin QFN T/R

The ZL38080 is part of Microsemi’s new Timberwolf audio processor family of products that features the company’s innovative AcuEdge acoustic technology, which is a set of highly-complex and integrated algorithms. These algorithms are incorporated into a powerful DSP platform that allow the user to extract intelligible information from the audio environment from which they are communicating. The Microsemi AcuEdge Technology ZL38080 is designed to provide leading edge Acoustic Echo Cancellation and Noise Reduction for the Hands-Free Automotive market. The Microsemi AcuEdge Technology license-free, royalty-free intelligent audio Firmware provides AEC, NR and a variety of other voice enhancements to improve both the intelligibility and subjective quality of voice in harsh acoustic environments such as high wind noise, engine and road noise. The MiTuner Automatic Tuning Kit and ZLS38508 MiTuner GUI provide automatic tuning and easy control for manual fine tuning adjustments. Further, the ZLS38508 MiTuner GUI provides easy graphical control of the various interconnections required to meet the needs of your application.
