Notebook SigmaTel audio programs

SigmaTel (SigmaTel, NASDAQ trading symbol: SGTL) today announced a new series of High Definition (HD) Audio Codec (Codec), the series supports digital microphone capabilities and OPA27GP datasheet and the ability to directly in the PC motherboard implement audio and OPA27GP price and modem functions.

In these new audio solutions, SigmaTel STAC9202 and OPA27GP suppliers and STAC9251 has digital microphone capabilities; and STAC9250 companies with Silicon Laboratories (NASDAQ trading symbol: SLAB) the Si3080 line-side modem direct access arrangement (DAA) chip with When used for motherboard audio modem technology (A-MoM) to support the deployment. The new High Fidelity HD Audio Codec enables notebook PC manufacturers to maintain the effective management of costs while allowing for the system to increase the advanced features.

STAC9202 and STAC9251 solution enables PC manufacturers and designers to easily design with built-in digital microphone, notebook computers, to improve the Voice (VoIP) telephone service, voice instant messaging (IM) and voice recognition applications voice input. Digital microphones do not require shielded analog cable microphone enables high-definition audio input, thus greatly reducing design complexity and assembly costs. Smaller number of microphones, and can optimize the LCD bezel acoustic layout, thereby reducing the traditional analog microphone noise. To develop a complete digital microphone solution, SigmaTel and digital microphone leader Akustica carried out close cooperation.

Wang Yi, president and CEO of SigmaTel Ron (Ron Edgerton), said: "Our customers are always required without sacrificing the quality of products, continue to lower system costs, improve system performance and flexibility. SigmaTel to required to provide its digital audio solutions, to significantly improve customer performance. Our new digital microphone and audio-modem main board is to reduce costs while achieving further evidence of the new features. in the integration require more notebook PC with high design, the designer can use the STAC9250 and STAC9251 the A-MoM technology will be integrated directly into the PC modem, motherboard, PC system without using a dedicated daughter card discrete devices. "

STAC9250 and STAC9251 audio codec with integrated Silicon Laboratories, modem interface technology. The integrated modem technical support and Silicon Laboratories DAA line side device connections, to achieve an industry-leading audio technology and PC modem combo chipset market, the perfect combination of technology. Designers can take full advantage of Silicon Laboratories DAA technology offers the companys high level of integration of external passive components, the smallest footprint, the best modem surge and thermal capacity to withstand and the lowest total cost of the modem program characteristics, implementation PC motherboard modem design. Silicon Laboratories Inc. is a silicon DAA solutions in the industrys most extensive experience with the company, its solutions provide customers with a more expensive traditional modem daughter card, reliable and easy to deploy alternative. DAA in full compliance with internationally accepted PTT, EMC and safety standards.
