Gennum Accelerates Migration to 3Gb/s SDI Video



    Reference Design and Development Board Reduces Development Time of 3Gb/s
SDI Solutions

    AMSTERDAM, NETHERLANDS, September 6 /CNW/ - (IBC 2007) - Continuing its
drive to enable high-performance 3Gb/s video, Gennum Corporation (TSX:GND) is
offering the industry's first reference design and development board to
deliver 3Gb/s transmission using existing dual-link equipment. This follows
the company's announcement of the industry's first 3Gb/s optical modules,
underscoring Gennum's leadership position in the 3Gb/s optical market. The new
reference design is being demonstrated at this week's IBC 2007, along with the
complete suite of Gennum's 3Gb/s offerings.

    "By combining our leading video broadcast components onto a single board,
we are enabling customers to rapidly develop, test and prototype 3Gb/s SDI
applications today with very little investment in time or resources," said
Martin Rofheart, Senior Vice President and General Manager, Analog and Mixed
Signal Division for Gennum. "This capability is key for many of our customers
that want to move to a single 3Gb/s link but have not had the internal
resources available to make the transition."

    Reference Design Delivers Unprecedented 3Gb/s Performance

    Gennum's new 3Gb/s reference design and development board converts a
SMPTE 372M dual link 1080p50/60 serial digital interface (SDI) signal to an
industry standard SMPTE424M-compliant 3Gb/s signal and vice versa. The
reference design leverages the company's broad portfolio of 3Gb/s products and
includes Gennum's equalizer, reclocker, cable driver, timing generator, clock
cleaner, dual optical receiver and transmitter. Customers may choose to
acquire the whole board, enabling test and evaluation of their 3Gb/s products,
or they may use the design as a reference in developing their products.

    The enhanced performance achieved by the reference design is due to the
combination of Gennum's video transport products used in the design, each of
which is optimized for 3Gb/s performance. Specifically, the reclocker results
in a solution with 0.8UI of input jitter tolerance. Similarly, the use of
Gennum's timing and clock cleaner solutions achieve better than 65ps output
jitter at 3Gb/s. Additionally, designers can choose to transmit over coaxial
cable or optical fibre, depending upon their application. Gennum's equalizer
and cable driver are optimized for coaxial transmission and its new optical
modules (dual optical receiver and dual optical transmitter) are optimized for
transmission over optical fibre.

    Applications Driving 3Gb/s SDI

    The demand for 1080p50/60 content creation is one of the key drivers for
higher capacity SDI transport. In addition, there is a growing desire to
produce high definition content at higher bit depths (12-bit per component)
and to provide support for R'G'B' and 4:4:4:4 processing. Unfortunately, the
bandwidth requirements to transmit these video formats in SDI form exceed the
capabilities of a single SMPTE 292M interface.

    To meet the needs for higher capacity video transport, both SMPTE (SMPTE
424M and 425M) and the ITU (ITU-R BT.1120 - 2005) have adopted the new
2.97Gb/s SDI interface, commonly referred to as 3Gb/s SDI.

    Targeting OEMs and ODMs of both professional and "prosumer" video
broadcast equipment, Gennum's new reference design enables fast and easy
migration to 3Gb/s for many applications, including, video cameras,
camcorders, DVRs/VTRs and 3Gb/s test signal generation.

    About the Demonstrations

    Gennum is demonstrating both the functionality of this new reference
design, as well as its new 3Gb/s optical modules, at the IBC 2007 exhibition,
which is open September 7-11.

    Pricing and Availability

    The reference design and reference board is anticipated to be available
in the fourth quarter of 2007.
