These algorithms are incorporated into a Council to minimize the environmental impact of electrical equipment. powerful DSP platform that allow the user to extract intelligible information from the audio environment. Microsemi AcuEdge Technology The Microsemi AcuEdge Technology ZL38040 device ZLS38040 Firmware is ideal for speakerphone and conference applications. Its license-free, royalty-free intelligent audio Firmware Full Narrowband and Wideband Acoustic Echo cancellation operation (ZLS38040) provides Acoustic Echo Cancellation (AEC), Noise Reduction (NR) and a variety of other Supports long tail AEC (up to 256 ms) voice enhancements to improve both the intelligibility Non-Linear AEC provides higher tolerance for and subjective quality of voice in harsh acoustic speaker distortions environments. Non-Linear processor Microsemi offers additional tools to speed up the G.168 Line Echo Canceller product development cycle. The MiTuner ZLS38508 Howling detection/cancellation or ZLS38508LITE GUI software packages allow a Prevents oscillation in AEC audio path user to interactively configure the ZL38040 device. The optional MiTuner ZLE38470BADA Automatic Advanced noise reduction reduces background Tuning Kit provides automatic tuning and easy control noise from the near-end speech signal using for manual fine tuning adjustments. Psychoacoustic techniques Keypad scanner (up to a 7x7 array) Applications Provisions for stereo audio mixing (sample rate of 44.1 or 48 kHz) and stereo music record and Full duplex Speakerphone for digital telephones playback (sample rate of 48 kHz) with 8 kHz or 16 kHz voice processing Echo cancellation for video conferences Comfort noise generation 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 2s complement (linear) G.722, G.711 A/ law Send and receive path equalizers 16-band for Narrowband mode 22-band for Wideband mode 44.1/48 kHz bypass mode Typical IP Speakerphone Application Cross Point Switch provides signal mixing 1 Microsemi Corporation Confidential and ProprietaryTimberwolf Digital Signal Processor family, powered by AcuEdge Technology Designed for IP Speakerphones ZL38040 Preliminary Data Sheet ZL38040 Hardware Features The MiTuner Automatic Tuning Kit and ZLS38508 MiTuner GUI DSP with Voice Hardware Accelerators Dual 16-bit digital-to-analog converters (DAC) Microsemi s Automatic Tuning Kit option includes: Sampling up to 48 kHz and internal output Audio Interface Box hardware drivers Microphone and Speaker Headphone amps capable of 4 single-ended or ZLS38508 MiTuner GUI software 2 differential outputs Allows tuning of Microsemi s AcuEdge 32 mW output drive power into 16 ohms Technology Audio Processor Impulse pop/click protection The ZLS38508 software features: 2 Digital Microphone inputs supporting Auto Tuning and Subjective Tuning support up to 4 Microphones Allows tuning of key parameters of the system 2 TDM ports shared between PCM and design 2 Inter-IC Sound (I S) Provides visual representations of the audio paths Each port can be a clock master or a slave with drop-down menus to program parameters, allowing: Each port supports delayed and non-delayed 2 (GCI) timing and I S normal and left justified Control of the audio routing configuration modes Programming of key building blocks in the Each port provides sample rate conversion transmit (Tx) and receive (Rx) audio paths and synchronous and asynchronous TDM Setting analog and digital gains bus operation Configuration parameters allow users to fine 2 SPI or I C Slave port for host processor interface tune the overall performance General purpose UART port for debug Master SPI port for serial Flash interface Boots from SPI or Flash Can run unattended (controllerless), self- booting into a configured operational state Flash firmware can be updated from SPI Slave Crystal-less operation (with a valid TDM clock) 14 General Purpose Input/Output (GPIO) pins 2 low power modes controlled by reset Performance AEC Tail Length: 256 ms AEC sampling rate: 8 kHz or 16 kHz Single-Talk Weighted Terminal Coupling Loss Tools (TCLw): > 60 dB ZLK38000 Evaluation Kit Double-Talk TCLw: > 40 dB MiTuner ZLS38508 and ZLS38508LITE GUI Double-Talk Attenuation: > 3 dB MiTuner ZLE38470BADA Automatic Tuning Kit Noise reduction up to 30 dB 2 Microsemi Corporation Confidential and Proprietary
