Product Overview

The CX20778 is a low-cost super wideband voice input processor for telepresence and long range voice pick-up webcam applications. This SoC features a high-fidelity stereo 16-bit ADC, microphone pre-amplifier, an asynchronous sample rate converter, a sync buffer, and Conexant’s award-winning DSP. The included advanced super-wideband voice processing algorithms deliver a crisp, clear, low-latency audio experience, that requires as little as two matched high-sensitivity unidirectional microphones. The flexible USB and I2S/I2C interfaces are ideal for integration in the high definition camera module, or directly inside the Skype-ready TV/STB.
