The CX20810, Conexant's new high-performance, HD voice capture IC is targeted to voice interactive products, voice conferencing systems, Skype TV/STB webcam and surveillance. The far-field audio ADC with pre-amp, maximizes the signal-to-noise ratio of the microphone’s input path with a constant, low gain across a range of up to five meters. The IC has a significant dynamic range of 106 dB and maximizes the signal quality to avoid saturation while maintaining the SNR from the microphone. When used in an acoustic echo cancellation system, the device maintains the SNR of a low-level voice signal while avoiding echo saturation. Featuring an internal bi-quad for noise filtering and mic array matching, the IC also provides high resolution digital and analog gain control over a wide range. A microphone array with up to four synchronized ADCs and programmable preamplifiers are each facilitated with their own dedicated microphone bias supply. Evaluation kits are available for $199, with pricing for the CX20810 ICs beginning at $0.90 each/10,000.
