Timberwolf Digital Signal Processor family, powered by AcuEdge™ Technology Designed for the Hands-Free Automotive market ZL38080 Product Brief Description Document ID# 149152 December 2014 Ordering Information 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. 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. Applications • Version 3 • Wideband and Narrowband Acoustic Echo Cancellation (AEC) • Full or Half duplex operation, supports long tail AEC (up to 256 ms) in both Narrowband and Wideband operation • Non-linear echo cancellation provides higher tolerance for speaker distortions • Advanced Noise Reduction (NR) reduces background noise from the near-end speech signal using Psychoacoustic techniques • G.169 Automatic Level Control (ALC) • Automatic Gain Control (AGC) • Provisions for stereo audio mixing (sample rate of 44.1 or 48 kHz) and stereo music record and playback (sample rate of 48 kHz) with 16 kHz voice processing • Howling detection/cancellation • Hands-Free Phone and Audio capability for Automotive applications Prevents oscillation in AEC audio path • Dynamic Range Compression • Continuous double talk convergence • Comfort noise generation • Long Silence detection • Mute function • Programmable tone generation (DTMF) • Various encoding/decoding options: • • 16-bit 2’s complement (linear) • G.722, G.711 A/μ law Send and receive path equalizers • 16-band for Narrowband mode • 22-band for Wideband mode • 44.1/48 kHz bypass mode • Configurable Cross-Point Switch 1 © 2014 Microsemi Corporation.

ZL38080 Product Brief ZLE38080 Evaluation Kit The ZLE38080 Evaluation Board is designed to aid and speed up the evaluation of the Microsemi AcuEdge™ Technology ZL38080 Hands-Free Automotive Audio Processor with the Microsemi AcuEdge Technology ZLS38080 Firmware. 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.
