(2) A network device that supports multiple switching and routing protocols. PMC-Sierra (Nasdaq:PMCS PMCS PMC Sierra (stock symbol) PMCS Project Management Control System PMCS partial mission-capable, supply (US DoD) PMCS Preventive Maintenance Checks & Services PMCS Professional Military Comptroller School ) today announced the addition of two new devices to their POS-PHY Level 3(TM) physical layer portfolio for data streams from OC-3 to OC-48. The PM5358 S/UNI-4x622 for multi-port OC-12 line interfaces, and the PM5382 S/UNI-16x155 for multi-port OC-3, combine serializer-deserializer (SERDES See serializer/deserializer. ), clock recovery and clock synthesis, together with SONET framers, packet and cell processors to achieve the highest level of integration currently available. These multi-functional devices replace up to nine discrete devices A discrete device (or discrete component) is an electronic component with just one circuit element, either passive (resistor, capacitor, inductor, diode) or active (transistor or vacuum tube), other than an integrated circuit. in next-generation, high-speed communications systems, simplifying equipment design and reducing time-to-market for super routers and multiservice switches. "With the introduction of both the S/UNI-4x622 and S/UNI-16x155, PMC-Sierra continues to set new standards for levels of integration and overall performance in standards-compliant, broadband silicon," said Steve Perna, vice president and general manager, PMC-Sierra's Optical Networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. Division. "These devices enable our customers to terminate the millions of up-links from DSLAMs, Access Concentrators, CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment Routers, Edge Routers and Multiservice Switches, for aggregation onto the high-speed Internet See broadband. backbones." Significant time-to-market savings obtained using PMC-Sierra's POS-PHY Level 3 architecture PMC-Sierra's family of POS-PHY Level 3 devices enable customers to deploy a single POS-PHY Level 3 link layer device that can support 16xOC-3c, 4xOC-12c, OC-48c, channelized Refers to an architecture that transmits data in channels. It often refers to the 64 Kbps channels in T1 lines, which were originally developed to handle digitized voice streams (TDM). See TDM. OC-48, channelized 4xOC-12, channelized 16xOC-3 and 2xGE termination (see table 1). This architecture enables customers to mix and match their line cards according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. service providers' network system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. (see figure 1). Using a single link layer device for traffic policing, fault management and performance monitoring results in significant time-to-market savings for next-generation, high-speed, multi-rate network interfaces required for edge, enterprise and core switches and routers.

"Xilinx worked closely with PMC-Sierra to be the first FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. company to have a production release of a POS-PHY Level 3 core," said Dennis Segers, senior vice president of the Advanced Products Group at Xilinx. "These new products from PMC-Sierra are an indication of the wide-spread adoption of POS-PHY Level 3 as an interface of choice for gigabit routers, terabit and optical cross connect switches and a wide range of SONET/SDH transmission systems. For these systems, standard silicon products and high-performance FPGAs, using standards-compliant cores, will enable designers to focus design effort on system differentiation, preserving system time-to-market." Leveraging PMC-Sierra's Extensive High-Speed CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. Mixed-Signal Expertise The S/UNI-4x622 supports four OC-12 channels and the S/UNI-16x155 supports sixteen OC-3 channels, both with on-chip clock recovery and clock synthesis. Both devices are the first at the OC-12 and OC-3 rates to implement the industry standard's 32-bit, 104 Mhz POS-PHY Level 3 System interface. The two devices are also pin and software compatible enabling customers to design one board for both OC-3 and OC-12 system interfaces with a stuffing option for optics. By enabling a single board design for multiple line rates, the devices greatly reduce design time-to-market. The 2.5 volt, all-CMOS devices achieve the lowest power in the industry. Unique Optical Fiber Protection Capabilities In addition, both devices feature a bi-directional 4-bit 622 MHz automatic protection switching (APS) interface for line card protection. Optical fiber facility protection between ports on the same line card is provided through an internal cross-connect, allowing customers to offer redundancy at different functional and price points (see figure 2). Pricing, Packaging and Availability The PM5358 S/UNI-4x622 will be sampling in December 2000 and the PM5382 S/UNI-16x155 will be sampling in February 2001. Volume pricing for the S/UNI-4x622 is set at $299 and for the S/UNI-16x155 at $429. Both devices are characterized for the industrial temperature range operation (-40(Degree)C to +85(Degree)C) and are implemented in-low power 2.5 Volt CMOS technology with 3.3 Volt tolerant inputs.
