Conexant Systems introduces two new speakers-on-a-chip (SPoC) system solutions for audio applications, covering converged audio and voice applications, from speaker-equipped control bases to internal communication systems Converged audio and voice applications for intercom doorbells and unified communications audio systems. The CX20662 and CX20663 can also be integrated with any analog audio system for full-duplex, hands-free speakerphone functionality. The new SPoC solution is now available in volume quantities to customers in the US, Europe and Asia.

René Hartner, vice president of marketing for Conexant Imaging and PC Media, said: "Our new on-chip speaker solutions further strengthen our position as a leading supplier of audio solutions, extending our use of our SPoC devices for speaker functionality. Market share of next-generation products such as smartphone docking stations. We will continue to leverage our extensive IP portfolio and expertise in voice processing and coding technologies to deliver innovative solutions for the growing audio market."
The CX20662 and CX20663 are designed for both mono and stereo applications, respectively, using Conexant's proprietary wideband echo attenuation and noise reduction digital signal processor (DSP) to capture a wide range of voice signals and produce a more natural sound. Voice. This technology reduces the “echo†and audible feedback from the speaker to the microphone, which is especially important for hands-free phones and VoIP applications. The two highly integrated devices also feature dual integrated audio codecs and programmable microphones to boost functionality for amplifying sound, headphone drivers and Class D amplifiers. In addition, the SPoC can operate without an external microcontroller. These functional combinations reduce material costs and speed up the product development cycle.
To improve the sound quality of intercom applications, the CX20662 integrates a line echo suppression DSP that reduces the echo caused by the telephone network or twisted pair structure lines. Conexant also provides an internal communication reference design to simplify product development.
For the smartphone docking system, the CX20663 can easily and quickly switch from hands-free phone mode to stereo music playback mode for MP3 music. Another important feature is Conexant's 3D technology, which uses a proprietary psychoacoustic phase virtual algorithm to “reconfigure†the sound field to create an immersive or extended “stereo segment†audio experience for the listener without adding realism. Audio traffic.
Conexant's innovative audio portfolio includes HD audio ICs, HD audio codecs and on-chip speaker solutions for PCs, PC peripheral sound systems, speakers, laptop docking stations, VoIP speakerphones, internal communications, Intercom doorbell and audio monitoring applications.
Packaging, supply and pricing
The CX20662 is available now in a 40-pin quad flat no-lead (QFN) package. The device is priced at $2.50 each in 10,000-piece quantities. The CX20663 is available in a 48-pin QFN package and is priced at $2.91 each in 10,000-unit quantities.
