1 / 35 page  03/11/15 Conexant Confidential • www.conexant.com 001DSR01 General Description The CX20921 is a high-performance, far field voice input processor System-on-Chip (SoC). The CX20921 is the first product in this category with an integrated voice trigger function that supports a low system power Wake- on-Voice (WoV) function. The device includes 24-bit microphone Analog-to-Digital Converters (ADCs), a powerful dual core 32-bit hardware Digital Signal Processor (DSP), and integrated power management. Combined with Conexant’s AudioSmart™ far field voice input processing software suite, including Smart Source Pickup (SSP) noise suppression and full-duplex Acoustic Echo Cancellation (AEC), the CX20921 is the ideal turnkey solution for adding voice control, voice search, and Voice over Internet Protocol (VoIP)/speakerphone functionalities to SmartTV, Set-Top Box (STB), Smart appliances, and automotive hands-free control and communication systems. The CX20921 device supports a microphone array with up to two synchronized ADCs and programmable pre- amplifiers. Each pre-amplifier is paired with a dedicated bias supply to eliminate crosstalk. The entire input path guarantees 106dB dynamic range, which maximizes speech-to-noise ratio with low boost and prevents microphone saturation. Conexant's proprietary far field AudioSmart software takes advantage of the built-in hardware to deliver a superior voice interactive experience in the most challenging room environments. The voice processing chain also supports multi-thread processing streams, which are independently optimized for voice communication and automatic speech recognition. When ADC and DSP are active in the Wake-on-Voice (WoV) mode, the device consumes less than 70mW, which is well below the 0.5W European Commission (EC) 1275/2008 requirement for standby power. Applications • Voice-controlled Smart TV/STB • Smart Bluetooth/WiFi speaker • Voice interactive smart appliance • Internet of Things (IOT) devices • Automotive hands-free control/communication Features • Low-power WoV mode with an embedded third-party speech recognition engine • Enables high-performance Automatic Speech Recognition (ASR) and excellent voice clarity with only two microphones through Conexant's AudioSmart voice input processing software, which includes: – SSP noise suppression – Full-duplex AEC • Compatible with multiple leading embedded and server-based speech recognition vendors • Dual far field, 24-bit, 106dB dynamic range ADCs with microphone pre-amplification and independent Microphone Bias (micbias) supply—enables low microphone gain for far field signals without saturating for loud near field signals • Powerful, dual-core 32-bit DSP • Multiple Integrated Interchip Sound (I2S) serial data interfaces • Inter-Integrated Circuit (I2C) serial control interface • Serial Peripheral Interface (SPI) for low-cost flash support CX20921 Far Field Voice Input Processor SoC AudioSmart Data Sheet |
