Industry Overview
Communications semiconductor products are a critical part of network infrastructure equipment. Network infrastucture OEMs require advanced communications semiconductor products — such as low-power, multi-core digital signal processor (DSP) SoC solutions, as well as switching and signal timing and conditioning solutions —that are highly optimized for the equipment employed by their customers. We seek to provide semiconductor products that enable network infrastructure OEMs to meet the needs of their service provider and enterprise customers in terms of system performance, functionality and time-to-market.
Addressed Markets
Our semiconductor products are primarily focused on network infrastructure equipment applications in three areas of the broadly defined communications network: enterprise networks, broadband access service areas, including wireless and wireline infrastructure networks, and metropolitan and wide area networks. The type and complexity of network infrastructure equipment used in these network areas continues to expand, driven by the need for the processing, transmission and switching of digital voice, data and video traffic over multiple communication media, at numerous transmission data rates and employing different protocols.
Enterprise networks include equipment that enables voice and data communications and access to outside networks, and is deployed primarily in the offices of commercial enterprises, including specialized commercial segments, such as broadcast video production, which have demanding network requirements. An enterprise network may be comprised of many local area networks, as well as client workstations, centralized database management systems, storage area networks (SANs) and other components. In enterprise networks, communications semiconductors facilitate the processing and transmission of voice, data and video traffic in converged IP networks that are replacing the traditional separate telephone, data and video conferencing networks.
Typical network infrastructure equipment found in enterprise networks that use our products include voice and media gateways, IP private branch exchanges, SAN routers, director-class switches and emerging enterprise-class wireless base station systems for enhanced mobile enterprise service delivery. In addition, a major trend in the broadcast video segment of the enterprise networking market is the switch from analog to digital television transmission and the conversion from standard-definition television services to high-definition television (HDTV) services featuring more detailed images and digital surround sound. We offer a family of broadcast-video products optimized for high-speed HDTV routing and production switcher applications.
Broadband Access service areas of the telecommunications network refer to the “last mile” of a telecommunications or cable service provider’s physical network (including copper, fiber optic or wireless transmission), including network infrastructure equipment that connects end-users (typically located at a business or residence) with metropolitan and wide area networks. For this portion of the network, infrastructure equipment requires semiconductors that enable reliable, high-speed connectivity capable of aggregating or disaggregating and transporting multiple forms of voice, data and video traffic. In addition, communications semiconductors must accommodate multiple transmission standards and communications protocols to provide a bridge between dissimilar access networks; for example, connecting wireless base station equipment to a wireline network, and enabling the computationally complex processing that is required in order for carriers to meet cellular data service demands with limited available spectrum. Typical network infrastructure equipment found at the edge of the broadband access service area that use our products include optical node units, optical line terminals, remote access concentrators, digital subscriber line (DSL) access multiplexers, mixed-media gateways, wireless base stations, digital loop carrier equipment and media converters.
Metropolitan and Wide Area Networks refer to the portion of a service provider’s physical network that enables high-speed communications within a city or a larger regional area, including inexpensive mobile backhaul services for wireless communications carriers. In addition, this portion of the network provides the communications link between broadband access service areas and the fiber optic-based, wide area network. For metro equipment applications, our communications semiconductors provide transmission and processing capabilities, as well as information segmentation and classification, and routing and switching functionality, to support high-speed traffic from multiple sources employing different transmission standards and communications protocols. These functions require signal conversion, signal processing and packet processing expertise to support the design and development of highly integrated mixed-signal devices combining analog and digital functions with communications protocols and application software. Typical network infrastructure equipment found in metro service areas that use our products includes add-drop multiplexers, switches, high-speed routers, digital cross-connect systems, optical edge devices and multiservice provisioning platforms.
The telecommunications network, including the Internet, has evolved into a complex, hybrid series of converging digital and optical networks that connect individuals and businesses globally. These new higher bandwidth, data-centric networks integrate voice, data and video traffic, operate over both wired and wireless media, link existing voice and data networks and cross traditional enterprise, broadband access, metro and long haul service area boundaries. Network infrastructure OEMs are designing faster, more intelligent and more complex equipment to satisfy the needs of service providers as they continue to expand their network coverage and service offerings while upgrading and connecting or integrating existing networks of disparate types. In this demanding environment, we believe network infrastructure OEMs select as their strategic partners communications semiconductor suppliers who can deliver advanced products that provide increased functionality, lower total system cost and support for a variety of communications media, operating speeds and protocols.
