The continued growth in Internet access bandwidth is driving service provider upgrades to metro networks to support greater capacity. To facilitate this expansion, system vendors require highly integrated, fully standards compliant, off-the-shelf silicon solutions to enable the rapid migration of DS-3 to OC-3 access links. To meet these needs, the S/UNI-1x155 occupies the industry's smallest board area, while providing the most integrated functionality and full standards compliance. Where current solutions require two devices to support ATM or POS (1) See point of sale and packet over SONET.

POS - point of sale , the S/UNI-1x155 incorporates both and allows selectability in a single design. All of this improves system design flexibility, provides time-to-market advantages, and reduces overall system power and cost for Packet-over-SONET (POS) and ATM-based networking equipment.
The S/UNI-1x155 is ideal for packet and ATM interfaces in applications such as 3G wireless base stations, CPE-based routers and DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. uplinks (see Figure 1 and Figure 2). The S/UNI-1x155 provides a highly integrated single-channel OC-3 (155 Mbit/s) SONET/SDH framer that combines a dual-mode Packet-Over-SONET frame processor and ATM cell processor with integrated clock recovery and clock synthesis, with three selectable system interfaces (POS-PHY Level 2, 16-bit UTOPIA Level 2, and 8-bit UTOPIA Level 2). The S/UNI-1x155 jitter performance meets all Bellcore GR-253 intrinsic jitter, jitter tolerance, and jitter transfer specifications. In addition, the S/UNI-1x155 features a bi-directional automatic protection switching (APS) interface for line card protection (see Figure 3).
"PMC-Sierra's S/UNI-1x155 expands our industry leading S/UNI family of products, providing POS and ATM network interface solutions from OC-1 to OC-192," said Glenn Bindley, vice president and general manager of PMC-Sierra's Internet Routing Division. "By maintaining software and hardware compatibility with the more than 1000 existing S/UNI designs we continue to focus on accelerating customer time-to-market," concluded Bindley.
The S/UNI-1x155 is packaged in a 15 mm by 15 mm, 196 pin stPBGA package. The S/UNI-1x155 is implemented in low power 0.25 micron, 3.3/2.5 volt 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. technology, providing typical power consumption of less than 400 mW. It is priced at $33.75 in 1K volume through distribution, with samples available in August 2001.
PMC-Sierra is accelerating the broadband revolution. PMC-Sierra's extensive family of broadband communication semiconductors enables the equipment that makes up the backbone of the Internet. PMC-Sierra offers worldwide technical and sales support including a network of offices throughout North America, Europe and Asia.
