Gennum Delivers World’s Fastest Crosspoint Switch

October 26, 2010

Supports Data Rates in Excess of 14 Gbps, Integrates CDR for
Best-in-class Signal Integrity

BURLINGTON, ON, Oct. 26 /PRNewswire/ – Gennum Corporation (TSX: GND), a leading
supplier of high-speed optical, analog and mixed-signal semiconductor
solutions, today introduced the industry’s first 2×2 crosspoint switch
capable of supporting data rates in excess of 14 gigabits per second
(Gbps) per port. In addition, the new GX4002 crosspoint is the first to
integrate a CDR (clock and data recovery), providing a single-chip
solution that satisfies the high-speed signal integrity requirements of
next-generation equipment used in data center, enterprise and
telecommunications networks.  The crosspoint is ideal for use as a
redundancy switch, repeater or high-speed loop-back monitor.

“Gennum has applied its rich heritage in advanced signal integrity
technology to achieve data rates never before possible on a crosspoint
switch,” said Martin Rofheart, Senior Vice President and General
Manager of Analog & Mixed-Signal Products at Gennum.  “We have also
advanced crosspoint functionality with the integration of our proven
CDR technology, applying innovative signal conditioning techniques to
ensure high quality, long distance signal transmission at these
breakthrough speeds. Our integrated solution reduces chip count and
complexity, saving both BOM cost and board space–all the while
delivering the world’s fastest crosspoint.”

The device provides the speed, bandwidth and signal integrity required
to support network equipment based on standards like 10 Gbps SONET
(OC-192); 10 Gbps Ethernet; 16 Gbps Fibre Channel; and Infiniband DDR
(double data rate), QDR (quad data rate) and FDR (fourteen data rate).

Resets Jitter Budget, Delivers High-speed for Redundancy, Redriver

With an integrated CDR that uses input equalization and output
de-emphasis for signal conditioning, the GX4002 reduces jitter and
allows high-speed signal transmission across longer distances.  Used to
restore and clean digital signals at extremely high speeds, the
integrated CDR “resets” the jitter budget, effectively erasing the
signal distortion that can occur during transmission across “lossy”
media such as copper cables and backplanes.  The GX4002 provides
unprecedented output jitter of 7 picoseconds, peak-to-peak (ps p-p).

In redundancy switching applications, the two-port switch allows
designers to create two identical 14 Gbps paths and use one channel for
protection switching in the event of a network failure.  An alternate
traffic path can be switched over and operational within 100
microseconds for OC-192/OTU2 data rates.

The GX4002 can also be used as a “redriver” or “repeater” to extend the
distance that a signal can be reliably carried across a backplane or
I/O card.  Finally, the device can be used for high-speed loop-back
support, enabling designers to monitor signal quality and diagnose
potential network problems.

As an asynchronous switch, the GX4002 can support different data rates
or protocols on each port.  A non-blocking design allows connection of
any input to any output for maximum design flexibility.

Extends Gennum’s Crosspoint Switch, Data Communications Offering
Gennum continues to set milestones in crosspoint technology, having
recently announced the world’s largest video crosspoint switch, the
GX3290, which offers 290×290 crosspoints at 3.5 Gbps (www.gennum.com/about/press/2010/gennum-unveils-world-s-largest-most-feature-rich-video-crosspoint-switch).

The GX4002 also complements Gennum’s growing portfolio of products for
next-generation networking, data center, storage and telecommunications
applications.  The company offers a full line of transimpedance
amplifiers (TIAs), clock and data recovery (CDR) solutions, laser
drivers and ROSAs for optical networking.

Pricing and Availability
The GX4002 is sampling now with full volume production slated for Q1
2011. The IC is packaged in a 32-pin QFN package and is expected to be
priced at $19.15USD each in volumes of 1,000.
