IDT Introduces Low Power High Definition Audio Codec Optimized for Superior PC Audio Experience

Codec and Advanced Software Significantly Improve Audio for Enterprise Notebook and Desktop Systems

IDT™ (Integrated Device Technology, Inc.)(NASDAQ:IDTI), a leading provider of essential mixed-signal semiconductor solutions that enrich the digital media experience, today introduced a new high definition PC audio codec, the first codec designed and developed by IDT since the close of the acquisition of the product line last summer. The new IDT device is a low power, high fidelity audio codec designed to help bring home-entertainment-level audio fidelity to enterprise desktop and notebook systems, while supporting mobile user capabilities such as advanced processing for voice over Internet protocol (VoIP). IDT PC audio solutions allow users to experience digital audio media through the devices’ unique combination of high-fidelity hardware, intuitive applications software, and worldwide OEM support.

The IDT 92HD71B features 4 stereo channels, and is compatible with the Intel high definition (HD) audio interface. The audio device provides stereo 24-bit resolution with sample rates up to 192 kHz. The dual digital SPDIF outputs enable simple integration with multi-channel consumer entertainment equipment, including audio integration with system HDMI video. The codec incorporates IDT proprietary technology to achieve digital to audio conversion signal-to-noise ratio fidelity in excess of 100dB. It also includes extensive optimizations to minimize unwanted audio artifacts, such as “pops”, during system power up.

In addition to high-fidelity, low power devices, the IDT PC audio solution provides a flexible, easy-to-customize graphical user interface (GUI), an audio effects designer program enabling system designers to optimize their system characteristics, and numerous audio processing capabilities required for home entertainment, VoIP, or other audio computing applications. As a result, IDT PC audio solutions enable OEM customers to maximize battery life, offer advanced usage models for PC audio, provide their end-customers the ability to personally manage the quality of their audio experience, and achieve high-levels of overall audio fidelity, compatible with the most stringent Windows Logo Program fidelity requirements.

“IDT is pleased to bring to market our new audio codec solution. IDT continues to make significant investments in its audio offerings – we’ve strengthened our product and software development capabilities in Asia, added significant customer support capabilities around the world, augmented the software environment and capabilities, and incorporated IDT low-power and mixed-signal expertise and technology into our audio devices,” said Phil Bourekas, vice president and general manager of the IDT PC Audio operation. “The 92HD71B is the first wholly IDT-developed device since we entered the PC audio market. Coupled with our advanced software, which enables customers to uniquely customize their design, the device drastically improves the PC audio experience and adds system value for our customers.”

The 92HD71B and software supports full-duplex stereo audio and simultaneous VoIP telephony by supporting multiple, independent audio streams. Additionally, the optimized and flexible power management, including driver optimizations and specialized audio circuitry mitigates pop/click sound anomalies, offering a smoother audio experience. The audio solution provides a mono output for laptop sub-woofer and support for 1.5V and 3.3 high definition audio signaling with run time selection to enable the widest possible range of system designs.
