Lyrtech launches OBSAI/CPRI Virtex-4 Development Platform



A flexible, integrated, and cost-effective platform for proven and established Xilinx OBSAI and CPRI reference designs

Quebec City, Canada (June 19, 2007). Lyrtech Inc. (Lyrtech) (TSX Venture Exchange:
LYT), a worldwide leader in digital signal processing technologies, announced today the
launch of the OBSAI/CPRI Virtex-4 Development Platform. At the heart of the platform are
the new Xilinx OBSAI RP3/RP3-01 and CPRI reference designs that were developed by Xilinx
as part of its 3G Wireless Base Station Initiative.

According to Dell’Oro, the base station market is already at the $20 billion level and
In-Stat projects 14% annual growth through 2009. The Open Base Station Architecture
Initiative
(OBSAI) and the Common Public Radio Interface (CPRI) are two industry
initiatives formed by major wireless OEMs such as Nokia, Samsung, LG Electronics, Ericsson
AB, Huawei Technologies, NEC Corporation, Nortel Networks SA, and Siemens AG. These
initiatives endeavor to develop industry standards and create open markets for cellular
base stations that will allow manufacturers and component vendors to share a common
protocol, more easily adapt their products from one customer to another, and reduce
structure costs.

“Xilinx and our host of blue-chip partners are an integral part of Lyrtech’s strategy
— helping us extend our reach, support a broader set of customers, and develop new
specialties in specific technologies and markets so we can offer our customers more
complete solutions,” said Migüel Caron, President and CEO of Lyrtech. “We look
forward to more collaborative initiatives.”

The Lyrtech OBSAI/CPRI Virtex-4 Development Platform allows users to create flexible
CPRI and OBSAI RP3/RP3-01-compatible data sources, sinks, and bus translation bridges for
serial RapidIO and Gigabit Ethernet interfaces. The platform also allows users to design
high-speed serial OBSAI/CPRI data connections from the onboard, high-performance clock
circuitry.

“Base station and remote radio unit OEMs are increasingly making CPRI and OBSAI
interfaces a definite requirement. With the introduction of the OBSAI/CPRI Virtex-4
Development Platform and available reference designs, Lyrtech and Xilinx can significantly
reduce engineers’ development time on OBSAI and CPRI applications,” said Amit Dhir,
director, Infrastructure Vertical Markets at Xilinx.

Benoit Fleury, Lyrtech’s Vice President of Sales and Marketing commented that, “Lyrtech
is proud to be recognized once again by Xillinx as an industry-leading partner in the
development of the OBSAI/CPRI Virtex-4 Development Platform. Wireless is one of Lyrtech’s
key expertise and focus areas, and this OBSAI/CPRI project further builds on our
leadership in wireless design solutions.”
