IDT Introduces Audio Subsystem with Integrated Programmable Clock Generator
21ic IDT® (Integrated Device Technology, Inc.) introduces the world's first audio subsystem with integrated programmable clock generator for portable applications. The new device integrates to minimize board space, reduce system cost, and reduce time-to-market by eliminating the need for long-term external crystals and oscillators.

The ACS42200 product line includes a low-power, high-fidelity codec for portable applications such as tablets, portable game consoles, personal navigation devices, portable projectors and speaker docks. The device also integrates four programmable system phase-locked loops (PLLs) for internal and external required clocks, DDXTM Class D amplifiers, true capacitor-free headphone amplifiers, advanced built-in audio processing capabilities for 3D applications, and bass And treble enhancement.
Patrick Griffith, Senior Marketing Director, Analogs and Power, IDT, said: "Integrating ultra-efficient DDX technology with industry-leading clock IP technology is a great example of IDT's ability to create value with analog and digital advantages. Integrated programmable phase-locked loop (PLL), high efficiency and high fidelity audio can solve the challenge at once, making the final product better, smaller, cheaper and faster to reach consumers. The ACS42200 extends IDT's computing audio portfolio to further enhance IDT is a vendor that supports the transition from laptops to tablets."
Four integrated programmable system phase-locked loops (PLLs) are unique to the IDT codec solution, providing timing management for system application processors, USB interfaces, auxiliary audio, and other subsystems, eliminating system designers Large, expensive crystals and oscillators that require long lead times are often required. At the same time, the integrated spread spectrum capability eliminates electromagnetic interference. In addition, IDT's patented DDX Class D amplifier technology delivers higher efficiency and lower power consumption than traditional binary Class D amplifier solutions, significantly extending battery life—a key requirement for next-generation portable consumer electronics.
The programmable DSP filtering engine complements these benefits by enriching the sound range with dynamic processing, balance, speaker protection and higher speaker volume when using small volume speakers. IDT also offers comprehensive Linux and Android system drive support and tuning tools for faster time to market, flexibility in speaker selection and industrial design.
The FirstPower CFPV(2V) and LFPV(6V/12V) series stationary batteries (Opzv Battery) are the newly products which were developed at the end of 2005.
The performances meet the standard DIN40742 and IEC60896 TubularPositive plate, gel electrolyte, PVC-SiO2 and redundant design makes the battery the most reliable battery. The design life is more than 20 years.
