Conexant Systems, Inc. introduced an ultra-low power, high-performance HD Audio CODEC targeted at mobile PC applications including notebooks, ultrabooks and tablets. The new CX8200 “intelligently drives speakers to optimize sound pressure level (SPL) while providing best-in-class speaker protection and eliminating background noise,” said the company.
A single-chip solution optimized for use on any platform with an integrated speaker, Conexant’s CX8200 uses a proprietary “SoftAware” link to interconnect amplifier hardware sensors with software algorithms. The dataflow between hardware sensors and software enables dynamic updates to the algorithms performing speaker control and Acoustic Echo Cancellation functions, which is said to improve overall system performance.
Part of the AudioSmart 2.0 product family, the CX8200 features a fully integrated Class-D smart amplifier and interfaces directly with Conexant’s software to deliver “flawless” speech recognition and audio output that is up to several times louder using existing PC/tablet speakers. Conexant said its AudioSmart 2.0 solutions improve the audio experience in noisy, real-world conditions and allow for a more natural collaboration experience with crystal clear playback and no background noise.
The CX8200 features a ProCoustic capless stereo headphone output that includes offset calibration to eliminate pops and clicks. Integrated headset support includes CTIA/OMTP auto-detect and switch functionality. Inline command sensing and multi-button headset detection enable control of third-party applications, system wake, and satisfies Google requirements for Chromebook. Up to four digital microphones can be connected with integrated boost and DC offset removal, and smart microphone interfaces are supported for Wake-on-Voice applications.
