New family of audio SoC solutions from Conexant for embedded audio apps

Conexant has introduced the CX2070X, a new family of audio system-on-chip (SoC) solutions targeting embedded audio and voice applications such as multimedia IP phones, personal navigation devices, portable media players, and mobile Internet devices. Additional applications include MP3 player docking stations, PC speaker systems, audio headsets, and unified communications systems that support services such as voice-over-IP telephony, speakerphone, and audio conferencing functionality.

The CX2070X SoCs include an integrated audio/voice digital signal processor (DSP), multi-bit codec, digital and analog input/out interfaces, and a 2.5-watt per channel Class-D amplifier to drive stereo speakers or optional post-width modulation (PWM) and differential line-out for external speaker systems amplifiers.

"We have applied our extensive expertise in voice- and audio-enhancing algorithms to deliver a next-generation speakers-on-a-chip product family that allows us to expand our reach into growing, adjacent embedded audio and voice segments," said René Hartner, vice president of marketing for Conexant. "These innovative solutions feature a powerful suite of Conexant developed technical innovations that dramatically improve audio and voice quality, and the user experience. In addition, an easy-to-use software configuration tool allows developers to customize audio systems and optimize listening experiences."

The key features of the CX2070X SoCs are,

Sub-band acoustic echo cancellation algorithm eliminates speaker-to-microphone feedback while preserving natural sounding voice for high-quality, echo-free voice conversations

Beam-forming can be used to confine the microphone pick-up radius for private conversation, or to capture a 360-degree radius for conference call applications

Two unique dynamic noise reduction filters for the incoming and outgoing audio streams eliminate ambient near- and far-end noises

Advanced line echo filter that eliminates echo from twisted-pair crossover on a full duplex two-wire hybrid network

Boost loudness without clipping, and match speakers for up to 2.5-watt channel
configuration

3-D Phantom speakers to create a closer-to-live sound experience
3-D virtual immersion to create an immersive surround effect and a headphone-like experience

Package: 76-pin quad flat no-lead (QFN) package
Price: Range from each $2.25 to $3.75 for 10k pieces
Availability: Now
