Device OPN Package Packing ZL38060LDF1 ZL38060LDG1 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 ZLS38060 Firmware The Microsemi AcuEdge Technology ZL38060 is designed to provide advanced Acoustic Echo Cancellation (AEC) and Noise Reduction (NR) for Connected Home applications. 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. 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. • Wideband and Narrowband Acoustic Echo Cancellation • Full or Half duplex operation, supports long tail AEC (up to 256 ms) in both Narrowband and Wideband operation • G.168 Line Echo Canceller • Non-linear echo cancellation provides higher tolerance for speaker distortions • Advanced NR reduces background noise from the near-end speech signal using Psychoacoustic techniques • Keypad scanner (up to a 7x7 array) • Signal mixing • Applications • 44.1/48 kHz stereo music playback with 8 kHz/16 kHz voice Howling detection/cancellation • Intercoms • Security systems • Continuous double talk convergence • Integrated smart home gateways • Comfort noise generation • • • • Connected Wallpad Block Diagram Prevents oscillation in AEC audio path Telephone signal detection and generation • Programmable tone generation (DTMF) • DTMF receiver • Caller ID Type 1 & 2 detection • Call Progress tone detection 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.

Connected devices could include integrated smart home gateways, intercoms, Media Centers, IP Cameras, or Skype. Microsemi AcuEdge™ Technology enables the full duplex operation between the connected devices to deliver on seamless high definition (HD) voice communication. In complex noise environments such as gaming rooms and building lobbies, Microsemi’s AcuEdge Technology cancels echo, maintains a constant ambient noise (comfort noise) and continuously converges during double-talk situations.

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. ZLE38060 Evaluation Board The Evaluation Kit (OPN ZLE38060BADA) is a fully contained design consisting of the ZLE38060 Evaluation Board with USB cable, headset with extension cable, and a speaker. The ZLE38060 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 ZLE38060 Evaluation Board. 4 © 2014 Microsemi Corporation.
