Conexant Systems introduced the world's first ultra-wideband (SWB) voice input processor system-on-chip (SoC) CX20708. This brand-new single chip is designed for home telepresence systems and voice recognition, and is an ideal solution for next-generation smart TVs and video game consoles.
This highly integrated chip has SWB voice processing algorithm features that provide a comfortable, clear, fully bidirectional, low-latency audio experience. In addition, CX20708 is an "Skype TV certified" audio component. This new chip complies with Skype's strict performance and quality specifications, including high voice-to-noise for natural voice and long-distance voice pickup up to 5 meters Ratio and average evaluation score.
For smart TVs and other applications that are introducing voice interaction as a viable human-machine interface requirement, quality of experience (QoE) is crucial to the success of a product. With its leading position and proprietary voice processing technology, Conexant has developed CX20708 to help original equipment manufacturers (OEMs) overcome the acoustic, mechanical, and electrical technology aspects of integrating voice input into modern living room electronics challenge.
A recent report by In-Stat entitled "Global Market of Networked 'Smart' CE Equipment" indicates that the development and use of smart TVs is expected to increase rapidly in the next 5 years. As a result, shipments of networked intelligent CE equipment are expected to increase sixfold, with over 230 million devices installed in 2014. The company also expects that in 2015 the shipment of smart TVs (supporting online applications) will exceed 50% of the global shipments of all network-based intelligent CE equipment.
Dr. Sailesh ChitTIpeddi, President and CEO of Conexant Systems, said: "We are closely monitoring the development of the integration of TV and communications equipment and expanding our audio expertise to meet the increasing number of smart TVs worldwide Demand. Our proprietary voice processing algorithms for ultra-wideband provide our customers with accurate audio Solutions that can comprehensively improve the user experience, and we are very pleased that our audio solutions have been certified with Skype TV Certificate of approval stamp. "
CX20708 SoC is a highly integrated chip with high-fidelity 16-bit ADC, microphone pre-amplifier, asynchronous sample rate converter, synchronous buffer, etc. It is Conexant's award-winning digital signal processor.
The main performance includes:
â— I2S / USB interface-in the high-definition camera module, inside the TV or set-top box is perfectly integrated
â— Integrated SWB voice processing-to ensure the highest performance voice quality
â— Long-distance on-site pickup microphone and beam forming-long-range hands-free phone and voice recognition function are used together with the best performance of 2 microphone array system
â— Integrated microphone pre-amplifier, ADC and DSP-single-chip voice input
â— Subband Acoustic Echo Cancellation-for full two-way speech recognition
Supply, packaging and price
CX20708 samples and evaluation boards are now available to qualified OEM / ODM customers. The SoC is produced in a 9x9 mm, 76-pin, quad flat, lead-free package made from environmentally friendly RoHS and green materials. The sample price is 1,000 pieces of order price, each piece is 3.00 USD.
The automotive wiring harness is the network body of the automotive circuit, and there is no automotive circuit without the wiring harness. Wiring harness refers to the contact terminal (connector) made of copper punched and crimped with the wire and cable, and then the outside is pressed with an insulator or an external metal shell, etc., and the wiring harness is bundled to form a component connecting the circuit.
