10/26/2004 - With the introduction of three digital audio networking processors from its CobraNet Silicon Series of products, Cirrus Logic Inc. (Nasdaq: CRUS) is making it possible for commercial and professional audio manufacturers to significantly lower costs of deploying networked audio systems. CobraNet technology is the defacto industry standard for delivering uncompressed digital audio over Ethernet networks, and with the new ICs — the CS181002, the CS181012 and CS181022 — Cirrus Logic expects to foster the creation of new markets and applications that can benefit from CobraNet-enabled digital audio networking processors.
With these new and future CobraNet-enabled ICs, Cirrus Logic is breaking from the traditional digital networked audio model of providing manufacturers with higher-cost module solutions. With a CobraNet IC-based approach, manufacturers can now create much simpler and significantly cost-reduced solutions. This product mix ensures the right IC solution for such different market applications as ceiling speakers, mixers, power amplifiers, signal processors, intercom systems, power amplifiers and paging systems. CobraNet-enabled products can be used in a wide variety of settings including recording studios, live performances, broadcast studios and commercial "installed-sound" facilities such as office buildings, hospitals, airports, music halls, sports arenas, restaurants and houses of worship. To further reduce costs of installing CobraNet-ready systems, the licensing fees that apply to the high-channel capacity CM-1 reference design have been eliminated for CobraNet silicon customers.
"By integrating CobraNet technology into silicon, and eliminating the former licensing and royalty-based business model, Cirrus Logic is dramatically lowering the cost per node for developing and installing digitally networked audio capabilities into existing and newly installed Ethernet networks," said David Parker, senior marketing manger for CobraNet Technology, Cirrus Logic. "That, in turn, expands the market for CobraNet-enabled ICs into new classifications of commercial and professional products that seek to benefit from the industry's leading networked audio standard."
"The new CobraNet Silicon Series ICs allowed us to introduce our new NM 1 which includes power over Ethernet (PoE), bi-directional audio and data transport, a studio-grade phantom-powered mic preamp and a single channel power amplifier in a compact, economical package," said Greg Duckett, director of Engineering at Rane Corporation. "All audio data, control data and power connections to the NM 1 are via a single CAT-5 cable and the product is fully IEEE 802.3af compliant as a Powered Device. The NM-1 has two RJ-45 Ethernet connectors for redundant CobraNet and PoE connections, with power and CobraNet redundancy being independent. The mic preamp gain is remotely controlled via SNMP. Integrating the CS-181012 CobraNet IC into our design simplified the development and allowed us to shorten the delivery schedule without compromising performance."
Cirrus Logic's CobraNet Silicon Series simplifies the design process and helps to reduce the overall bill of materials for manufacturers using standard, proven Ethernet network cabling and equipment. The CobraNet Silicon Series delivers high-quality, uncompressed digital audio even over long distances. Because CobraNet technology co-exists with Ethernet data and voice-over-IP traffic already present on any given facility's network infrastructure, it is considerably more cost effective to implement compared to installing a dedicated digital audio network.
CobraNet technology delivers networked audio, control and monitoring — key features in installations where control, flexibility and/or reliability are highly valued.
The CS181002 supports two channels of simultaneous audio in/out; the CS181012 supports eight channels of simultaneous audio in/out; and the CS181022 supports sixteen channels of simultaneous audio in/out.
