Noise cancellation and sound enhancement
in a BGA
Full-duplex hands-free audio processor is now available in a small-footprint package for applications such as mobile handsets where size and power constraints are critical.
Acoustic Technologies has released its patented SoundClear technology in a small 5 x 5mm BGA package The new BGA package is offered for the company's ATH3101 chip, a highly integrated full-duplex, hands-free audio processor that improves voice clarity through acoustic echo cancellation, noise cancellation and sound enhancement

Chip clears up hands-free car kits
The ATH3001 hands-free car kit (HFCK) full-duplex integrated circuit is designed for improved sound quality in hands-free applications.
The small footprint package is ideal for applications such as mobile handsets where size and power constraints are critical.
"Working together with our mobile handset customers, we determined the need for a smaller footprint solution that included all of the echo cancellation, noise reduction, audio enhancement, and full-duplex performance features of our existing SoundClear IC", said Jim Jacot, Vice President of Sales and Marketing at Acoustic Technologies.
"The small footprint BGA package is ideal for mobile handsets and other applications requiring small size, low power, and the highest quality audio".
All advanced features of the ATH3101 are included in the BGA package option including: dynamic gain control for microphone and line inputs, 10-band graphic equalisers, bidirectional noise reduction, programmable gain input amplifiers and output drivers with fully differential signalling, dual 16bit sigma-delta codecs sampling and side-tone cancellation.
The device is easily adapted to different plastic designs and acoustic configurations and supports close speaker to microphone distance.
With low power dissipation and multimode power management, the ATH3101 is ideal for mobile handsets and other small form factor applications.
The ATH3101 does not require a microcontroller and the chip uses a pin controller for volume levels.
Fast and easy audio analysis and tuning is provided by Acoustic's eXcho diagnostics and tuning tool featuring an easy-to-use GUI.
This tool supports quick and efficient development that allows users to easily optimise and tune for specific plastics, transducers, and audio configurations.
The ATH3101B BGA is sampling now and will be available in production quantities in the second quarter of 2007.
