Speakerphone chip boosts VoIP sound quality
The ATH3003 is a VoIP full-duplex speakerphone integrated circuit for improved sound quality in VoIP applications.
Acoustic Technologies SoundClear products combine acoustic echo cancellation, noise cancellation, sound enhancement, and network echo cancellation with sophisticated monitoring and control techniques to enable full-duplex speech and improved voice clarity.
The full-duplex operation provides rich, clear, enhanced sound with no clipping or distortion.
SoundClear optimises speech intelligibility with full-duplex control that dynamically monitors, detects and processes incoming voice, echo, and noise signal power levels.
Key performance features of the ATH3100 device include up to 65dB of acoustic echo cancellation, 45dB of network echo cancellation, and up to 18dB of noise cancellation.
The ATH3100 integrates dual voice-band codecs and digital PCM interfaces for integration flexibility.
Sound quality is enhanced by the ATH3100 10-band graphic equalisers, spectrally matched comfort noise and AGC functionality for both the microphone and line inputs.
In order to simplify phone system design, the device also includes support for both handset and speakerphone modes, DTMF generation, ringer tone generation and caller-ID demodulation Type I and Type II.
The ATH3100 device provides optimal speech intelligibility using patented sound enhancement techniques to increase audio fullness and presence.
"The ATH3100 is a complete integrated solution supporting full-duplex voice processing with integrated telephony features for high quality speakerphone applications", said Bob Ackmann, CEO of Acoustic Technologies.
"Market leaders continue to adopt SoundClear technology for their leading edge telephony products and the ATH3100 is a great addition to our portfolio of IC and software products for those companies needing a single chip solution for their speakerphone products".
"Key partners will be announcing new products based on the ATH3100 soon".
The device is tunable to specific applications, casings, and user preferences via the eXcho tuning toolset.
In addition, eXcho enables faster time to market with easy diagnostics and real-time tuning capability on the PC based GUI interface.
The ATH3100 is highly configurable and includes customisable settings that can be evaluated and optimised in real-time using the eXcho tool.
The ATH3100 is available for immediate sampling in a 48-pin LQFP package and will be available in a 48-pin QFN package in late 1Q06.
All devices use green packaging and are RoHS compliant.
An evaluation kit and eXcho tuning tool are available now to provide everything customers need to evaluate the system and quickly bring their speakerphone products to market.
Acoustic Technologies also offers acoustic consulting services for helping customers optimise their speakerphone designs.
