PMC-Sierra Introduces Three New Devices to Enable High-Speed Interfaces
for Multi-Service Equipment

VANCOUVER, British Columbia, Jul 26, 2000 (BUSINESS WIRE) --

S/UNI(R)-STAR, S/UNI(R)-CDB and S/UNI(R)-4xD3F devices
increase system flexibility and time-to-market advantages
for edge & access networking equipment

PMC-Sierra (Nasdaq:PMCS) today announced three new broadband communication
devices, providing physical layer processing for next generation access and
metro-based equipment.

These new chips are ideal for network equipment such as DSLAMs, customer premise
equipment (CPE) based routers, access multiplexers, and wireless base stations.
The new PM5352 S/UNI(R)-STAR, PM7339 S/UNI(R)-CDB and PM7349 S/UNI(R)-4xD3F
chips improve system design flexibility, speed time-to-market and reduce overall
system cost for packet and ATM based networking equipment.

Highly integrated silicon solutions are necessary to facilitate the expansion of
service provider networks via DWDM and SONET/SDH based transmission systems. In
addition, interfaces into these networks require greater capacity and traffic
handling capabilities. To facilitate this expansion, semiconductor solutions
targeting customer premise equipment are migrating from T1/E1 rates to T3/E3
rates and those targeting DSLAM equipment from DS-3 to OC-3 uplinks.

"While current system development efforts focus on OC-48, OC-192 and beyond, it
is critical that we continue to enable our customers to design and build
world-class multi-service equipment with T1/E1, T3/E3, and OC-3/STM-1
connections for today's multi-layered, multi-rate network," said Travis Karr,
Product Manager, PMC-Sierra's Optical Networking Division.

New Solutions for DSLAM and Wireless Base Station Equipment

The S/UNI-STAR is targeted at packet and ATM interfaces for applications such as
DSLAM up-links (see figure 1), CPE based routers and switches and wireless
base-stations. The device is a highly integrated single-channel OC-3 (155
Mbit/s) SONET/SDH framer that combines a dual-mode Packet-Over-SONET (POS) frame
processor and ATM cell processor with integrated clock recovery and clock
synthesis. The S/UNI-STAR's jitter performance meets all Bellcore GR-253
intrinsic jitter, jitter tolerance and jitter transfer specifications. The
S/UNI-STAR is also designed to be pin and software compatible with PMC-Sierra's
PM5349 S/UNI-QUAD and PM5351 S/UNI-TETRA devices, preserving existing software
investments and an easy migration path to four-channel devices.

The S/UNI-4xD3F chip provides four physical layer interfaces for packet-based
equipment, integrating four DS3 framers. Additionally, the device provides E3
and J2 framer support that can be independently configured with DS-3 for
multi-service flexibility. By enabling a single board design to accommodate all
three rates, the S/UNI-4xD3F greatly reduces design time for next-generation
multi-service equipment, customer premise equipment routers and wireless base
stations (see figure 2). The S/UNI-4xD3F is also designed to be pin and software
compatible with PMC-Sierra's PM7347 S/UNI-JET and PM7346 S/UNI-QJET devices,
preserving existing software investments.

The S/UNI-CDB is a fully UTOPIA Level-2 standard compatible, four-channel, cell
delineation block device that can operate up to a maximum speed of 52 Mbit/s.
The device provides the Physical Layer Convergence Protocol (PLCP) for DS-1,
DS-3, E1 and E3 transmission systems. Support is provided for ATM direct mapping
into various rates up to 52 Mbit/s. Targeted at quad-channel applications such
as DSLAM Access equipment (see figure 3), Internet Access Devices (IAD) and
wireless base stations, the S/UNI-CDB provides the cell delineation needed in
these ATM based applications. The S/UNI-CDB is also designed to be pin and
software compatible with PMC-Sierra's PM7347 S/UNI-JET and PM7346 S/UNI-QJET
devices, preserving existing software investments.

Pricing, Packaging and Availability

The S/UNI STAR, S/UNI-CDB and S/UNI-4xD3F are available in production quantities
now. Pricing is set for high volume quantities at $53 for the S/UNI-STAR, $65
for the S/UNI-CDB, and $89 for the S/UNI-4xD3F. All three devices are
implemented in low power 3.3 volt CMOS technology with 5 volt tolerant inputs.
The S/UNI-CDB and S/UNI-4xD3F are implemented in 256-pin SBGA packages, while
the S/UNI-STAR is implemented in a 304-pin SBGA.
