ZL38063 Microphone Array ASR-assist Audio Processor The ZL38063 is part of Microsemi's Timberwolf audio processor family of products that improves Automatic Speech Recognition (ASR) performance at extended distances with barge-in capability and is optimized for detecting voice commands. The Microsemi AcuEdgeTM Technology ZL38063 device is specifically designed for televisions, set-top boxes, and smart speakers, but works equally well in other connected home applications. The device is capable of both voice control and 2-way full duplex audio with voice enhancements such as Acoustic Echo Cancellation (AEC), Noise Reduction (NR) to improve both the intelligibility and subjective quality of voice in harsh acoustic environments. Microsemi offers additional tools to speed up the product development cycle. The MiTunerTM ZLS38508 or ZLS38508LITE GUI software packages allow a user to interactively configure the ZL38063 device. The optional ZLE38470BADA Automatic Tuning Kit provides automatic tuning and easy control for manual fine tuning adjustments. Applications Microsemi AcuEdgeTM Technology ZLS38063 Firmware The ZL38063 can run different Firmware images that target specific modes of operation. Firmware images can be swapped during normal operation to switch modes dynamically. Microsemi provides firmware images for two basic operational modes: Two way voice communication * Supports 2-3 microphone linear arrays for 180 audio pick up * Supports 3 microphone off-axis or triangular arrays for 360 audio pick up * Supports device cascading to allow up to a 6 microphones array * Full Narrowband and Wideband Acoustic Echo Cancellation (AEC) operation * Integrated smart home gateways * Supports long tail AEC (up to 256 ms) * Connected home devices: * Set Top Boxes * Non-Linear AEC provides higher tolerance for speaker distortions * Smart Speakers * Non-Linear processor * Digital Assistants Block Diagram * Noise reduction * Far-field microphone processing ASR Assist Algorithms * Supports 2 microphone linear arrays for 180 audio pick up * Supports 3 microphone off-axis or triangular arrays for 360 audio pick up * Supports device cascading to allow up to 6 microphones in a circular array for 360 audio pick up * Support for Barge-in, or incoming trigger 'spotting' in the presence of DAC audio output Ordering Information * Noise reduction * ZL38063LDF1: 64-pin QFN (9x9) package (Tape and Reel) * Enhanced far-field support for distances up to 16 feet from the microphone. * ZL38063LDG1: 64-pin QFN (9x9) package (Tray) * ZL38063UGB2: 56-ball WLCSP (3.1x3.1) package (Tape and Reel) These packages meet RoHS 2 Directive 2011/65/EU of the European Council to minimize the environmental impact of electrical equipment. ZL38063 Microphone Array ASR-assist Audio Processor Hardware Features * DSP with Voice Hardware Accelerators * SPI or I2C Slave port for host processor interface * General purpose UART port for debug * Master SPI port for serial Flash interface * Boots from SPI or Flash * Flash firmware can be updated from SPI Slave * 14 General Purpose Input/Output (GPIO) pins (11 with the 56pin WLCSP) * 2 low power modes controlled by reset The MiTunerTM Automatic Tuning Kit and ZLS38508 MiTuner GUI Tools Microsemi's Automatic Tuning Kit option includes: * MiTunerTM ZLS38508 and ZLS38508LITE GUI * Audio Interface Box hardware * MiTunerTM ZLE38470BADA Automatic Tuning Kit * ZLK38000 Evaluation Kit * Microphone and Speaker * ZLS38508 MiTuner GUI software * Allows tuning of Microsemi's AcuEdge Technology Audio Processor The ZLS38508 software features: * Auto Tuning and Subjective Tuning support * Provides visual representations of the audio paths with dropdown menus to program parameters, allowing: * Control of the audio routing configuration * Programming of key blocks in the transmit (Tx) and receive (Rx) audio paths * Setting analog and digital gains * Configuration parameters allow users to "fine tune" the overall performance Microsemi Corporate Headquarters One Enterprise, Aliso Viejo, CA 92656 USA Within the USA: +1 (800) 713-4113 Outside the USA: +1 (949) 380-6100 Fax: +1 (949) 215-4996 Email: sales.support@microsemi.com www.microsemi.com (c)2017 Microsemi Corporation.
