IDT Introduces World's First Portable Audio Subsystem with Integrated Programmable Clock Generator for Tablet Computing

IDT’s New Codecs Integrate Programmable PLLs to Save Valuable Board Space, Cost, and Improve Time-to-Market in Portable Applications

SAN JOSE, Calif., July 28, 2011 – Integrated Device Technology, Inc. (IDT®; NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced the world’s first audio subsystem with integrated programmable clock generator for portable applications. This new device minimizes board space and reduces system cost through integration, and provides time-to-market advantages by eliminating the need for multiple external crystals and oscillators that typically involve long lead times.  

          The ACS42200 family includes a low-power, high-fidelity codec targeted at portable applications such as tablet computers, portable games, personal navigation devices, portable projectors and speaker docks. The device also integrates four programmable system PLLs for internal and external timing, a DDX™ class-D speaker amplifier, a true cap-less headphone amplifier, and advanced built-in audio processing capability for 3D, bass and treble enhancement.

          “The integration of our ultra-efficient DDX technology and industry-leading timing IP is a perfect example of how IDT brings the analog and digital worlds together to create value,” said Patrick Griffith, senior director of marketing for the Analog and Power Division at IDT. “The integrated programmable PLLs and high-efficiency, high-fidelity audio solve several challenges at once, making the end-product better, smaller, cheaper, and in the consumer’s hands sooner. The ACS42200 extends IDT’s computing audio portfolio, well-positioning IDT to support the transition from notebooks to tablets.”

          The four integrated programmable system PLLs are unique to IDT’s codec solution and enable the timing management of a system’s applications processor, USB interface, secondary audio and other subsystems. This allows system designers to eliminate large, costly crystals and oscillators that can often cause procurement delays, while the integrated spread spectrum capability can eliminate EMI concerns. In addition, IDT’s patented DDX class-D technology offers higher efficiency, consuming less power than traditional binary class-D solutions. This results in a significant improvement in battery life – a critical demand of next generation portable consumer electronics.

          All of these advantageous features are further complemented by a programmable DSP filter engine that enriches the sound presence through dynamics processing, equalization, speaker protection, and louder volume when using small speakers. IDT also offers complete driver support and tuning tools for faster time-to-market with Linux and Android systems, and flexibility in speaker selection and industrial design.

Pricing and Availability
          The IDT ACS42200 family is currently sampling to qualified customers and is available in a 68-TLA (dual-row QFN) 6x6mm package. The ACS422Axx and ACS422Dxx offer analog or digital microphone support respectively, and the ACS422MAxx and ACS422MDxx are the mono speaker amplifier versions. The IDT ACS422Axx and ACS422Dxx are priced at $1.35 each, and the ACS422MAxx and ACS422MDxx are priced at $1.20 each, for volumes of 10,000 units. Factory programmed custom clock configurations are available for all options. For the needs of large markets or customers, IDT is able to rapidly customize this device to provide varying levels of integration, such as additional audio processing, more or fewer PLLs, etc. For more information, please visit
