PMC-Sierra Announces Industry's First 622 Megabit Per Second ATM Physical Layer Device with On-Chip Clock and Data Recovery and Clock Synthesis.BURNABY, British Columbia--(BUSINESS WIRE)--Dec. 8, 1998-- -- The highly-integrated S/UNI-622-MAX Enables Next-Generation ATM Port Adapters for High Speed, High Density Backbone Connections -- 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 introduced the PM5356 S/UNI(tm)-622-MAX, the industry's first 622 Mbit/s (OC-12c) framer and ATM cell processor, with integrated serializer-deserializer, clock recovery and clock synthesis on a single chip. The highly integrated S/UNI-622-MAX provides both Utopia Level 2 and Utopia Level 3 compatible system interfaces, enabling the next generation of high-speed port adapters for ATM switches, routers, remote access concentrators and up-links (www.pmc-sierra.com\Press_releases\622max_evolution.pdf). The S/UNI-622-MAX provides a single-channel 622 Mbit/s solution from optical transceiver to the Utopia system interface. Leveraging PMC-Sierra's extensive high-speed mixed-signal expertise, the device provides on-chip PLLs that exceed the Bellcore GR-253 intrinsic jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle and jitter tolerance WAN specifications. The 3.3 volt, all-CMOS S/UNI-622-MAX achieves power consumption of 2.8 watts, the lowest in the industry. "Our customers require the highest density solutions to meet the explosive demand for enterprise and Internet bandwidth," said David Blakeney, vice president of ATM switching at FORE Systems See Marconi. . "By integrating the analog front end with a framer and cell processor, the S/UNI-622-MAX combines the highest level of system integration with state-of-the-art clock recovery and clock synthesis," Blakeney continued. The S/UNI-622-MAX is the first device to implement an 8-bit, 100MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. Utopia Level 3 System Interface. This mode enables high-density OC-12c and 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 applications by reducing the pincount by almost 50 percent when compared to Utopia Level 2 implementations. For backwards compatibility backwards compatibility - backward compatibility with existing ATM layer and other switching products, a Utopia Level 2 interface is also provided on the S/UNI-622-MAX. The PM5356 S/UNI-622-MAX is characterized for the industrial temperature range operation (-40 to +85 degrees Celsius), and supports automatic protection switching (APS) through the processing of the K1, K2 SONET line overhead bytes. The device is sampling now in a 304 SBGA SBGA Striped Bass Growers Association SBGA Spreader Ball Grid Array SBGA Super Ball Grid Array package and is priced at $199 in one thousand unit quantities. The S/UNI-622-MAX connects directly to PMC-Sierra's PM7322 RCMP-800 ATM Layer cell processor and the PM73487 QRT QRT Quick Response Team QRT Quick Response Training QRT quick reaction team (US DoD) QRT Stop Transmitting (used in CW communications) QRT Quick Reaction Test (US DoD) / PM73488 QSE QSE Quality Software Engineering QSE Quality, Security, Environment QSE Estimated Drift of Survival Craft (radiotelegraphy) QSE Qatar Stock Exchange switching chipset, over an industry standard Utopia Level 2 compliant bus for seamless interoperability (www.pmc-sierra.com\Press_releases\622max_portcard.pdf). The S/UNI-622-MAX is also software compatible with PMC-Sierra's existing industry standard PM5355 S/UNI-622, enabling a smooth upgrade path for the large base of existing designs. "With the introduction of the S/UNI-622-MAX, PMC-Sierra continues to set the standard for new levels of integration, functionality and performance in silicon," said Tim Pezarro, marketing manager of the transmission and switching division at PMC-Sierra. "The end result is a next-generation port card solution that minimizes noise, improves jitter performance, and dramatically simplifies design and layout requirements," Pezarro concluded.
