Gennum Targets ''Prosumer'' Applications with New Video Solution

    Industry's First HD/SD-SDI Serializer with Integrated Audio Multiplexer

    BURLINGTON, ONTARIO, April 10 /CNW/ - Bringing advanced video
capabilities to a new class of applications, Gennum (TSX:GND) unveiled an
integrated serializer that targets emerging "prosumer" products such as
digital camcorders, mixers and recorders. The GS1582, which will be available
for sale in June 2007, features several enhancements over Gennum's previous
HD/SD-SDI serializers including the industry's first integrated audio
multiplexer. Gennum will be demonstrating the capabilities of the new device
showing both video and audio at the National Association of Broadcasters (NAB)
trade show (Booth SU9114) held April 16-19 in Las Vegas, Nevada.

    "Gennum continues to focus on silicon integration to deliver the highest
performance, lowest cost solutions for our customers," said Alan Ferguson,
Director of Marketing at Gennum. "By incorporating the audio multiplexer,
cable driver and ClockCleaner(TM) into our serializer, our customers' bill of
materials is dramatically reduced, enabling a host of new applications to take
advantage of serial digital interface (SDI) capabilities at an affordable
price point. As a result, we will continue to see more robust professional
video capabilities, such as SDI functionality, moving to the mainstream via
prosumer and consumer products."

    Embedded Audio Multiplexer

    The GS1582 is the industry's first high definition/standard definition
serial digital interface (HD/SD-SDI) serializer with an internal audio
multiplexer. Previously, customers used field programmable gate arrays (FPGAs)
for the multiplexer, adding considerable board space and cost to the overall
design. Gennum's patented innovation features an internal audio multiplexer
integrated with video processing for both HD-SDI and SD-SDI. Additionally, the
GS1582 is compliant to industry standards, including the Society of Motion
Picture and Television Engineers (SMPTE) 299M and SMPTE 272M-A/C. The device
supports up to eight channels of 48kHz audio, which supports Dolby 5.1 and is
required for many emerging prosumer applications today. The input audio can be
AES, I2S or serial digital audio, providing flexibility for designers
targeting a variety of applications.

    Internal Cable Driver, Low Power Consumption

    In addition to the integrated audio multiplexer, the GS1582 comes
equipped with an internal SMPTE-compliant cable driver with excellent output
return loss performance. Previously handled in a separate chip, the
integration of the cable driver represents a significant savings in cost,
board space and power consumption. Indeed, the GS1582 has the same power
consumption and package size as previous Gennum serializers even with the
addition of a cable driver and audio multiplexer. The device also features a
low-power standby mode, making it ideal for battery-powered applications, such
as camcorders.

    Internal ClockCleaner

    The GS1582 also features Gennum's acclaimed ClockCleaner technology,
which allows the device to tolerate a high-jitter input parallel clock and
still have a low-jitter serial output. Jitter rejection depends on the
frequency of the input jitter, but typically a serializer with Gennum's
ClockCleaner technology is capable of rejecting 10 times more jitter than any
other HD-SDI serializer. In the GS1582, this technology has been refined so
the loop bandwidth can be narrowed even further to as low as 20kHz, proving
further jitter rejection.

    Meeting the Needs of Prosumer Applications

    The GS1582 delivers considerable features over previous HD/SD-SDI
serializers making it ideal for a host of new applications. Specifically, the
GS1582 offers:

    --  Support for CEA 861 timing

    --  Generic ancillary data insertion

    --  Extended temperature range of -20 to +85 degrees C

    --  Improved output eye diagram

    --  New pin out that allows for easier noise-immune board design

    NAB Demonstration Showcases Unprecedented Serializer Performance

    Gennum's new serializer will be shown serializing video and multiplexing
audio for attendees at NAB next week. Specifically, the GS1582 will be
serializing parallel video and inserting embedded audio, highlighting the
chip's extremely low jitter performance.

    About Gennum's Video Timing and Transport Offerings

    Gennum offers a broad portfolio of semiconductor solutions for the video
equipment industry, including equalizers, cable drivers, reclockers,
serializers, deserializers, clock generators and cleaners and embedded audio
CODECs. The company received a Technical Emmy(R) Award at CES 2007 for its SDI
