Vitesse Unveils VScope(TM) Embedded Waveform Viewing Technology to Revolutionize Signal Integrity Analysis

Vitesse Semiconductor Corporation (Pink Sheets:VTSS) is providing
system designers with new possibilities to redefine the dynamics and
economies of backplane design, signal integrity analysis, test &
measurement equipment, and remote monitoring in communication systems
with the introduction of VScope(TM), a revolutionary Integrated
Circuit (IC)-based waveform viewing technology. VScope embeds the
oscilloscope function into the receiver of ICs used in communication
systems, thus offering direct viewing of signal characteristics
similar to traditional lab oscilloscopes.

Vitesse´s patented technology provides a more accessible and
cost-effective signal analysis tool that can be remotely monitored
through network connections. VScope technology leapfrogs current
signal integrity methods to scan the input data eye within the chip
itself and produces the industry´s first offering of true in-line
imaging of the real-time data stream on a per-pin basis.

"Vitesse´s approach to embedded waveform viewing technology will
certainly drive signal analysis across the network, resulting in
greater network reliability for end-users," said Will Strauss,
principal analyst for Forward Concepts. "They have brought to market a
solution that enables exceptionally high accuracy and newfound
visibility critical for cost-effective system debug and remote
monitoring. As well, the advanced ´micro-oscilloscope´ afforded by
VScope will spark the advent of new applications that go beyond the
reach of today´s lab scope functionality."

True Visibility of Signal Integrity

Vitesse´s VScope data acquisition architecture uses dual
adjustable sampling channels for simultaneously receiving and
scanning. VScope delivers superior accuracy over external measurement
methods, because it reflects the true behavior of the data stream as
it is captured, thus avoiding correlation errors between the
measurement circuitry and live data path. Post-equalizer scanning,
made possible with VScope, delivers an unobstructed view of the
internal IC signal compared to oscilloscopes that offer only an
extrapolated view of signals from outside the chip.

By replicating the oscilloscope function within the IC, the
equivalent of countless engineering test labs can now be deployed
throughout the network. This creates exceptional visibility in
monitoring signal integrity in ICs, systems, and networks. The same
monitoring function used during system development can now be used as
an ongoing health monitor for systems and networks. As an example,
deployed VScope-equipped systems can inform network operators of
signal health and failures, resulting in a newfound function of
continuous monitoring of signals to facilitate greater overall network
reliability.

"VScope is a game-changing technology that will bridge the gap
between test & measurement equipment capability and the demands of
signal integrity engineering," said Gary McCormack, chief
technologist, Signal Integrity Solutions, Office of the CTO for
Vitesse. "VScope will become an integral part of Vitesse´s
comprehensive portfolio of signal integrity solutions offering both
the capability to transport ever-faster signals across all types of
media and a revolutionary new way to verify signal integrity. Our
patented signal scanning architecture provides designers and network
engineers the vision they need to elevate data services to the next
level."

Vitesse to Present at DesignCon 2008

Vitesse will present a paper entitled "Design and Application of
Embedded Waveform Viewing Technology for Integrated Circuits" at
DesignCon 2008 the week of February 4-7, 2008, at the Santa Clara
Convention Center. Specific presentation time and conference
information can be found at the DesignCon website:
