IDT Expands Family of High Definition Audio Codecs

SAN JOSE, Calif.—(BUSINESS WIRE)—June 9, 2008— 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 member of its high definition PC audio codec family. The new device is a low power, high fidelity audio codec and is the first audio codec designed and developed by the IDT Shanghai design center. In addition, the device is manufactured in the IDT fabrication facility in Hillsboro, Oregon using 0.18 micron process technology to further reduce power consumption. Moreover, the device uniquely offers the industry increased design flexibility by achieving Windows Logo Program (WLP) compatibility in the smallest form factor currently available for a High Definition (HD) audio codec.

Similar to the existing members of the IDT PC audio codec family, the new IDT device is optimized 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.

We are excited about our new audio codec solution. Its nice to see the significant investments we have made in our PC audio solutions have resulted in product offerings that help establish IDT as a significant contributor to this market, said Mary Cunningham, director of marketing for the IDT PC audio operation. Like the other members of the IDT PC audio codec family, the 92HD75B is a low-power device that brings consumer electronics level-audio performance to both desktops and notebooks. Our goal for all our audio codecs is to improve the audio experience for the PC market while adding system value for our customers.

As with all members of the IDT PC audio codec family, the new device also includes the proprietary IDT HD sound graphical user interface (GUI) that enables customers to provide end-users with maximum, yet easy-to-use, control of a PC audio system through complete audio software customization. The HD sound GUI provides intuitive initial individual set-up, input/output audio jack configurability, and allows end-users to dynamically adjust their audio experience based on application, environment, and content. As a result, IDT PC audio solutions enable OEM customers to maximize battery life, offer advanced usage models for PC audio, and 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 WLP fidelity requirements.

The IDT 92HD75B is available in a smaller 32-pin QFN package enabling IDT customers a reduced footprint while maintaining high definition audio quality. The device features 2 stereo input and 2 stereo output channels and is compatible with the Intel high definition audio interface. It also includes extensive optimizations to minimize unwanted audio artifacts, such as pops, during system power up.

The 92HD75B, and related 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 3.3V high definition audio signaling with run time selection to enable the widest possible range of system designs.

Pricing and Availability

The IDT 92HD75B is currently sampling in the 32-pad QFN environmental (RoHS) package. Prices are listed at $0.95 for 10,000 units. For additional product information on IDT PC audio solutions visit
