This article refers to the address: http://

Following the introduction of the industry-leading CobraNet® network digital audio technology, Cirrus Logic relaunched the new product development platform CobraComTM. At the AES conference in San Francisco, USA, Cirrus Logic fully exhibited its CobraComTM platform designed to develop digital audio network equipment based on CobraNet technology.

CobraCom hardware uses standard Ethernet technology and the new IEEE 802.3af Power over Ethernet (PoE) standard, including Fast Ethernet-based CobraNet interface, speaker power amplifier, on-board microphone, external microphone input, general purpose I/O, RS-232 Serial port and PoE power. The CobraCom reference design features the CobraNet CS496012 audio system processor. The processor integrates a 32-bit professional audio digital signal processor (DSP) engine and CobraNet transmission to support local processing of audio signal in and out of auto-ducking, speaker zone equalization and ambient sound monitoring. PoE helps power network audio devices over the same CAT-5 cable. The CAT-5 cable is a channel for transmitting digital audio, system control information and network data, simplifying network installation, configuration and management. The rapid adoption of VoIP technology has made it possible to use PoE-enabled converters and network-powered CobraCom systems for mid-span power injectors.

Mr. Rus Sundholm, President of Attero Tech, said: "The flexibility of the CobraCom platform allows us to develop multiple network audio products with little or no modification. With thousands of CobraNet networks currently operating in the field, OEMs can Launched a network-powered CobraNet audio product in a few months."

CobraCom technology is also suitable for the development of commercial and household products. Typical devices that use CobraCom technology include intercoms, paging stations, network-powered speakers, and conference sites, all of which use CobraNet networks with unlimited area capacity.

Keith Cheney, vice president and general manager of embedded products at Cirrus Logic, said: "Cirrus Logic continues to innovate with CobraCom technology, leading the market with unique network digital audio products based on CobraNet technology. We created the CobraCom platform to represent network-powered audio. The added value of the product. CobraCom technology is the basis for a variety of innovative network audio products that serve the user's network edge."

As a ready-to-use reference platform, CobraCom design accelerates OEM product development cycles while reducing design and engineering investments. Cirrus Logic's DSP ConductorTM graphics development tool further simplifies the task of embedding complex audio signal processing in the platform's products. The customized CobraCom technology is very simple and supports fast implementation of higher or lower complexity devices while maintaining compatibility with CobraNet networks.

With more than 750,000 channels installed worldwide, CobraNet technology is the leading technology for delivering uncompressed digital audio over Ethernet.
