Microsemi Corp. has announced the first product in its Timberwolf family. Enabled by Microsemi's AcuEdge acoustic technology, the ZL38040 claims to deliver best-in-class high definition (HD) voice communication solutions for the enterprise hands-free speakerphone markets.

Microsemi's ZL38040 is a device with an advanced wideband acoustic echo canceller designed to provide leading-edge echo cancellation and noise reduction for HD audio speaker phone and IP phone applications. Microsemi's patented AcuEdge firmware and its acoustic echo canceller permit significantly more audio information to be transmitted while blocking interfering signals such as echo and background noise, stated the company.

AcuEdge's technology consists of license-free, royalty-free audio IP solutions. It is the compilation of various intellectual properties targeted at processing voice signals in conjunction with noise reduction algorithms, automatic gain control, echo cancellation, psychoacoustic noise reduction, howling detection and rejection. These capabilities are the foundation for enterprise level automatic speech recognition, sound classification and other intelligent decision-making functions based on sound and audio detection.

To complement the ZL38040 hardware and AcuEdge software, Microsemi provides a comprehensive development package to accelerate customers' time-to-market via a validated reference design and easy-to-use tools that include MiTuner, an automated AEC tuning kit. The Microsemi AcuEdge solution has been tested on customer platforms that meet TIA, ETSI and ITU standards, enabling the ZL38040 to achieve design-in success with tier-one OEMs in targeted enterprise markets.

The capabilities afforded by Microsemi's ZL38040 are important advancements to meet the increasing demand for IP phones and enterprise hands-free communication, the company added.
