Tuesday June 22, 5:01 am Eastern Time Company Press Release PMC-Sierra Introduces Industry's Most Integrated Packet Processors for Channelized Voice & Data Applications New FREEDM devices are the industry's first solutions able to process a fully channelized DS-3signal BURNABY, British Columbia--(BUSINESS WIRE)--June 22, 1999-- PMC-Sierra (Nasdaq:PMCS - news) today announced two new additions to the FREEDM family of high density packet processors -- the PM7380 FREEDM-32P672 and PM7381 FREEDM-32A672. The FREEDM-32P672 targets PCI-based system architectures typically used in Remote Access Concentrators while the FREEDM-32A672 is ideal for low latency, high performance applications such as Voice Over IP (VOIP) gateways and high density Frame Relay Interfaces. Each device supports up to 672 simultaneous High-level Data Link Control (HDLC) channels across up to 32 T1 or E1 links. The new FREEDM devices replace up to six HDLC processors using currently available solutions. Advanced System Interface Options The FREEDM-32P672 is the industry's first HDLC processor to support a 66 MHz, 32 bit PCI 2.1 compliant system interface, and allows system designers to continue to deliver high performance PCI-based solutions while leveraging the broad range of available PCI-compliant chips including ATM SARs, processors, bridges, encryption and compression devices. ''We worked closely with PMC-Sierra on the definition of the FREEDM-32P672 to ensure its feature set was well-suited for high performance remote access applications,'' said Trevor Schulze, Cisco Systems hardware development manager. The FREEDM-32A672 is the industry's first HDLC processor to support the new Any-PHY(TM) streaming packet system interface. The Any-PHY(TM) interface is a 16 bit, 50 MHz multi-point bus which supports high speed cell or packet data transfer for large numbers of channels. The interface is based on PMC-Sierra's industry standard POS-PHY specification used in Packet-Over-SONET (POS) interfaces. For applications such as Frame Relay or Voice Over IP, FREEDM's Any-PHY(TM) bus features support for aggregate data rates exceeding 622 Mbit/s, sustained traffic with small average packet size, and the ability to ensure low latency required for delay sensitive applications such as voice. FREEDM Applications Both new FREEDM products support a broad range of line interface rates -- ranging from 1.5 Mbit/s (T1) to 52 Mbit/s (HSSI). Each device can be directly connected to PMC-Sierra's high density PM4388 TOCTL Octal T1 framer, PM6388 EOCTL Octal E1 framer or to the PM7346 S/UNI-QJET Quad J2/E3/T3 framer. The many channelized DS-3 solutions currently using PMC-Sierra's PM7366 FREEDM-8 devices will be able to seamlessly upgrade to the new higher density FREEDM solution. Figure 1 illustrates the density improvement in this application by using the new 672 channel FREEDM devices with the PM4388-NI TOCTL (a new smaller package option for the PM4388-RI TOCTL). Figure 2 shows a next-generation PCI-based Remote Access Concentrator using the FREEDM-32P672. A high performance multi-channel DS-3 Frame Relay port card using the FREEDM-32A672 is shown in Figure 3. Pricing and Availability The PM7380 FREEDM-32P672 is packaged in a 31 by 31mm 329-pin PBGA and priced at $299 in 1KU volumes. The pin-compatible PM7381 FREEDM-32A672 is priced at $239 in 1KU volumes. General availability for both devices is planned for third quarter 1999. Each is rated for industrial temperature range operation (-40 to +85 degrees Celsius). Comprehensive Customer Support The FREEDM-32P672 and FREEDM-32A672 both utilize PMC-Sierra's proven TimePipe(TM) HDLC processor architecture to ensure an easy hardware and software upgrade path for the more than 100 existing designs currently using PMC-Sierra's first generation FREEDM-8 and FREEDM-32 devices. The software backward compatibility of the two new FREEDM devices provides FREEDM customers with a significant reduction in development effort and risk. A comprehensive customer support package including device datasheets, technical overview, programmer's guide and hardware reference design is available at pmc-sierra.com. ''PMC-Sierra is committed to providing our large base of current FREEDM customers with a very aggressive rollout of higher integration, software-compatible FREEDM products with enhanced features,'' said Glenn Bindley, PMC-Sierra's general manager, access products division. ''Our customers' requirements for very high HDLC channel capacities and higher performance system interfaces drove the development of these two new products,'' Bindley concluded.
