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. Device OPN Package Packing ZL38080LDF1 ZL38080LDG1 64-pin QFN (9x9) 64-pin QFN (9x9) Tape & Reel Tray These packages meet RoHS 2 Directive 2011/65/EU of the European Council to minimize the environmental impact of electrical equipment. Microsemi AcuEdge Technology ZLS38080 Firmware 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.

It provides a simple analog interface that can be connected to microphones and speakers in a plastic enclosure to allow for subjective testing of the Acoustic Echo Canceller. The miniature size allows for easy mounting in an existing plastic enclosure. Easy access to all analog and digital interfaces is provided. ZLE38080 Evaluation Board The Evaluation Kit (OPN ZLE38080BADA) is a fully contained design consisting of the ZLE38080 Evaluation Board with USB cable, headset with extension cable, and a speaker. The ZLE38080 Evaluation Board is controlled using the Microsemi MiTuner™ GUI Software (ZLS38508). The MiTuner GUI Software can also be used with the optional Microsemi Audio Interface Box (AIB) Evaluation Kit (OPN ZLE38470BADA) to auto tune the ZLE38080 Evaluation Board. 4 © 2014 Microsemi Corporation.
