10Gbps Networking Speeds Introduced
    SFP+ modules from Intel show dramatically improved signal integrity

    LAS VEGAS, May 21 /PRNewswire/ -- Fujitsu Booth #1931 -- Highlighting
dramatic performance improvements for networking applications, Fujitsu
Microelectronics America, Inc. and Gennum Corporation (TSX: GND) are
hosting a unique demonstration at this week's Interop tradeshow in Las
Vegas. The demonstration utilizes Fujitsu's innovative 10-Gigabit per
second (Gbps) serial interconnect, Intel Corporation's small form factor
pluggable (SFP+) modules and Gennum's industry-leading clock and data
recovery (CDR) chip. Showcasing a working 10-Gigabit Ethernet switch
solution with SFP+, this demonstration underscores the significant signal
integrity optimization achieved with the use of CDRs.
    "Our continued commitment to delivering superior optical networking
solutions is showcased in this demonstration today," said Asif Hazarika,
senior manager of the Networking Product Group of Fujitsu Microelectronics
America. "The combination of our switch chip with Gennum's ClearEdgeTM CDRs
delivers the best performance with the highest signal integrity for SFP+
applications."
    The innovative 10Gbps serial interconnect, based on the Fujitsu
MB8AA3020, connects directly to Intel's SFP+ optical module without any
additional circuitry in between. Gennum's CDR solution, comprised of the
company's 10-Gigabit Ethernet CDR ICs GN2023 and GN2024, is optimized to
work with high integration ICs, such as Fujitsu's, and supports modules,
such as Intel's 10GBASE-SR-compliant SFP+ optical transceiver enabling
higher density linecard designs. CDRs are used to ensure optimal
performance and relieve jitter budget concerns in SFP+ implementations,
enabling practical, low cost, integrated solutions.

    "While integration continues to play a key role in increasing port
densities and reducing cost, the signal integrity must be maintained to
meet the demanding performance requirements," said Bharat Tailor, marketing
and applications director, Data Communications Product Division for Gennum.
"This demonstration clearly showcases the tremendous benefit our CDRs bring
to SFP+ applications, while highlighting the benefits of Fujitsu's highly
integrated switch chip."
    "SFP+ is a critical emerging optical module form factor," said Scott
Schube, strategic marketing manager, Optical Platform Division, Intel. "By
demonstrating 'plug and play' performance with existing devices, such as
the Fujitsu ASIC and Gennum CDR, we are showcasing the opportunity for our
customers to have a validated solution today that can deliver the
performance required for high speed data communications applications such
as servers, routers and switches."
    SFP+ modules benefit from dedicated CDRs
    There is always uncertainty-or jitter-with the timing of any high-speed
signal. Using a CDR to "clean" the SFP+ signal improves the robustness of
the link and eases the high-speed performance requirements on the highly
integrated application specific standard products (ASSP) or application
specific integrated circuits (ASICs) that are generally interconnected with
the modules. The benefits of a dedicated CDR are showcased in the
demonstration, using one of the industry's most advanced switch chips to
deliver unprecedented 10Gbps performance with SFP+ modules.
    The SFP+ module shown in the demonstration highlights the benefits of
this emerging smaller form factor module, namely the increase in port
density and reduced overall cost that SFP+ brings to networking
applications such as data center and enterprise switches. Indeed, according
to market research firm CIR, the market for SFP+ transceivers will reach $1
billion by 2012, underscoring the dramatic growth that the SFP+ market will
experience over the next five years.

    About the demonstration
    Attendees at this year's Interop will see a 10-Gigabit Ethernet switch
demonstration with SFP+ highlighting the excellent signal integrity of a
CDR-based solution. Specifically, the demonstration shows a Fujitsu
MB8AA3020 evaluation board directly connected to Intel's
10GBASE-SR-compliant SFP+ optical transceiver, creating a switch system.
The transmission performance of the system is shown with and without CDR
functionality enabled. With the CDR enabled, error-free operation is
achieved at 10Gbps.
    Featured products

    -- Having shipped more than 800,000 CDRs worldwide, Gennum is the leading
       provider of CDRs for 10Gbps module applications. Gennum's latest CDR
       solution, comprised of the second-generation GN2023 Limiting Amplifier
       plus CDR IC and the GN2024 Equalizer plus CDR IC, can be utilized in
       both XFP and SFP+ optical modules supporting 10-Gigabit Ethernet
       applications; both devices operate from a 3.3V supply and do not
       require a reference. The CDR solution is based on Gennum's ClearEdgeTM
       technology, which offers enhanced performance and reduced power
       consumption. Gennum's GN2023 and GN2024 10-Gigabit Ethernet CDRs are
