Conexant Delivers Wideband Audio Chip for Smart TVs

Conexant Systems, a supplier of semiconductor solutions, has announced the CX20708 super wideband voice input processor system-on-chip (SoC). The new single chip solution is targeted to home telepresence and speech recognition applications and is ideally suited for next generation Smart TV and video game console applications.

The highly integrated chip features voice processing algorithms that deliver a full duplex, low latency audio experience. In addition, the CX20708 is a “Skype TV Certified” audio component, which ensures that the new chip meets Skype’s performance and quality specifications including high speech-to-noise ratio, Mean Opinion Score (MOS) for natural voice, and long distance voice pick-up of up to five meters in distance.

For Smart TVs, voice interaction is being introduced as a viable human interface requirement, where the Quality of Experience (QoE) is pivotal to the success of a product. Leveraging its proprietary voice processing technology, Conexant has developed the CX20708 to help OEMs overcome the acoustic, mechanical and electrical challenges of integrating voice input capabilities into modern living room electronic appliances.

The CX20708 SoC features high-fidelity 16-bit ADC, microphone pre-amp, asynchronous sample rate converter, sync buffer and Conexant’s digital signal processor. The I2S /USB Interface is ideal for integration in the HD camera module or directly inside the TV or set-top-box.
