Acoustic Technologies' SoundClear ATH3101 for Mobile Handsets.Now Available in Small Footprint 5 mm x 5 mm BGA (Ball Grid Array) A popular surface mount chip package that uses a grid of solder balls as its connectors. Available in plastic and ceramic varieties, BGA is noted for its compact size, high lead count and low inductance, which allows lower voltages to be used. Package MESA, Ariz. -- Acoustic Technologies, a leading developer of high quality full-duplex voice processing The computerized handling of voice, which includes voice store and forward, voice response, voice recognition and text to speech technologies. solutions, announced the release of their patented SoundClear[R] technology in a small 5mm by 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 The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. , Noise Cancellation (1) The elimination of unwanted signals in an electronic circuit. See noise and dynamic noise reduction. (2) The elimination of unwanted noise in the environment using noise cancelling headphones. , and Sound Enhancement. 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, Inc. "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 equalizers, bi-directional noise reduction, programmable gain input amplifiers and output drivers with fully differential signaling Using two wires for each electrical path for high immunity to noise and crosstalk. The signals are sent down one wire as positive and the other as negative, and the circuit at the receiving end derives the signal from the difference between the two. , dual 16-bit Sigma-Delta CODECs The following is a list of codecs. Audio codecs Non-compression formats
With low power dissipation and multi-mode power management, the ATH3101 is ideal for mobile handsets and other small form factor applications. The ATH3101 does not require a micro-controller and the chip uses a pin controller for volume levels. Fast and easy audio analysis and tuning is provided by Acoustic's eXcho[TM] diagnostics and tuning tool featuring an easy-to-use GUI (Graphical User Interface) A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant advantages of a GUI vs. a character-based interface. . This tool supports quick and efficient development that allows users to easily optimize 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.
