Gennum First to Drive 12Gb/s-SDI Over Optical

    Demonstrates Highest Speed and Performance to Support Industry's Move to
Emerging Video Standards

    CHIBA, JAPAN, November 19 /CNW/ - Continuing to showcase its innovative
solutions for video broadcast, Gennum Corporation (TSX:GND) demonstrates the
industry's highest speed, highest performance video transport leveraging its
optical technology. The unprecedented signal integrity achieved at 12 gigabits
per second (Gb/s) validates the video industry's ability to move to even
higher resolution video formats, to transmit multiple high rate streams across
a single optical link and to support emerging high rate standards. The
demonstration is being held at Gennum's booth at the International Broadcast
Equipment Exhibition (Booth 5601), November 20-22 at the Makuhari Messe
Convention Center.

    "Just as we did in the early days of SDI, Gennum continues to innovate in
order to enable our customers to move to the next level with their video
streaming applications," said Martin Rofheart, Senior Vice President and
General Manager, Analog and Mixed Signal Division. "This demonstration
highlights the broad possibilities for our video customers to move even higher
rates of video through their infrastructure. As important, new and emerging
standards such as Ultra-High Definition TV and D-Cinema are now within reach,
as these data rates will support the delivery of content that meet the high
quality requirements of these and other standards."

    Gennum's demonstration leverages the company's leading clock and data
recovery (CDR) technology for video optical module applications, which enables
the maximum signal integrity at these higher rates to deliver high quality
video. The module, a standard off-the-shelf XFP transceiver modified to
include Gennum's 12.5G CDR test chip, is capable of variable data rates from
9.9Gb/s to 12.5Gb/s. This variation enables support for a broad range of
current and emerging standards, such as UHDTV, Society of Motion Picture and
Television Engineers (SMPTE) 435M, D-Cinema, 12-bit 4:4:4 1080p. Additionally,
the high bandwidth enables up to eight HD-SDI links or four 3Gb/s-SDI links,
creating new possibilities for design of serial routing and distribution

    "We welcome demonstrations of this nature," said Peter Symes, Director,
Standards and Engineering, of SMPTE. "We expect to create standards and
specifications for motion picture applications at ever higher data rates, and
proof of concept is essential to the credibility and focus of the work."

    About the Demonstration

    Highlighting the tremendous performance gains that can be achieved using
CDR technology, Gennum's demonstration features a 13.5 Gb/s BERT (Bit Error
Rate Tester) which is used as a variable bit rate source and receiver. This
signal is electrically transmitted to the optical transmit module which
converts the data from electrical to optical. The optical signal is then split
into two optical signals. One signal goes directly to a high speed
oscilloscope for observation of the raw optical transmit eye. The other signal
is sent to the optical receive portion of the module. The signal is received
by the optical module and converted back to an electrical signal, at which
point it passes through the Gennum CDR which resets the jitter budget. It then
passes through the crosspoint and is sent to the oscilloscope. The
oscilloscope shows the significant differences in performance between a signal
that has passed through the CDR and one that has not, with the signal having
passed through the CDR showing an increase in performance.
