VELIO INTRODUCES NEXT GENERATION I/O
GRID TECHNOLOGY
GigaCore2 permits a doubling of backplane
speed,
enables new generation
Velio devices that scale to true terabit capacity and
eables platforms
to double in bandwidth.
Velio Communications Inc
announced GigaCore2, the next generation of its
industry-leading serial I/O
technology, which enables leading platform vendors
to scale the performance
and density of their high-speed datacom, storage and
telecom systems with
backplane speeds up to 6.25 Gb/s, all while maintaining
backward compatibility
with existing line-cards.
Doubling backplane speeds of existing
equipment is the next step for many
of the platform vendors, as most of their
end customers wish to maximize
the bandwidth and density of their existing
equipment instead of changing
platforms. Velio's original GigaCore I/O is
driving the many of the current
generation of systems with serial backplanes
in the range of 2.5 to 3.125
Gb/s, and GigaCore2 has innovations in the
technology that enable most of
the systems to double their system
bandwidth.
GigaCore2's signal integrity capability is proving itself
today in a number
of customer's backplanes, and is a key component of Velio's
next generation
product line, addressing Velio's current Telecom, Datacom and
Storage
customer bases.
Additionally, Velio is developing custom
products using GigaCore2 for some key
Top Tier customers.
"Velio is
delivering on our customer's requests to extend the lifetime of
their current
platforms," comments Raju Chekuri, CEO. "Their customers are
looking to extend
their investment as they double the bandwidth of their
platforms. Velio's
commitment to innovation in high speed I/O will deliver
the technology to make
this possible. We see a significant window of
opportunity for GigaCore2 to
enable a generation of higher bandwidth
systems using proven techniques."
Manufactured in 0.13 standard CMOS, GigaCore2 enables the development of
highly integrated switching ICs of up to 1 Terabit per second (up to
160x160
ports). Key attributes that are critical in such high-density chips
are low
power (20mW per Gb/s) and small die area. The technology is
tolerant of the
noise that occurs in VLSI environments. The GigaCore2 has a
wide operating
range to support legacy rates from 622 Mb/s through the next
generation 6.25
Gb/s. The ability to run the same I/O across multiple
generations also permits
easy system upgrades while preserving end
customer's investments in line cards
and port cards.
"The bandwidth and density demands by our Top Tier
customers for 6 Gb/s and
faster backplanes are real. Our customers also expect
the low power and
integration that they are used to, which would be difficult
to obtain if
they use a complex signaling scheme such as PAM. GigaCore2
achieves
excellent performance at these higher speed data rates using familiar
NRZ
coding," said Bill Woodruff, vice president of marketing for Velio.
Enhanced Equalization Techniques In Both The Transmitter and Receiver
GigaCore2 extends Velio's best-in-class equalization capability. The
GigaCore2
adds sophistication to its transmitter and receiver equalization.
Dividing the
responsibility for equalization between the transmitter and
the receiver
achieves superior overall performance.
"In order to build products
with 160 x 160 integration levels, each I/O has
to be robust under all
conditions. Circuit architectures and design
methodologies are chosen to
accommodate these stringent requirements," said
Ramesh Senthinathan, director
of Advanced Technology for Velio. "Robustness
for worst-case high integration
situations means additional design margin.
This means our I/O have the margin
to operate in legacy backplanes where
noise and crosstalk is present."
