CX20810 / CX20811

Product Overview

The CX20810 is a high performance, analog front-end, high-definition voice capture IC for voice recognition, control, and conferencing applications. The device supports a microphone array with up to four synchronized ADCs and programmable pre-amplifiers. Each pre-amplifier has a dedicated micbias supply that eliminates crosstalk. The entire input path guarantees 106dB dynamic range, which allows the voice system to use the full performance of a high SNR microphone using low microphone boost to prevent microphone saturation. This path is critical for far field applications, and also ideal for compact speaker-phone designs where the microphone and speakers are in close proximity.
