PALO ALTO, Calif.--(Business Wire)--
GigOptix Inc. (OTCBB:GGOX), a leading provider of electronic engines for the
optically connected digital world today announced successful results from
collaborative work with Prof. Bahram Jalali`s engineering group at UCLA on using
GigOptix`s LX8900 in a novel 110GHz time stretched analog-to-digital conversion
(ADC) application. 

Ultra-wide-band ADC is one of the most critical problems faced in communication,
instrumentation and radar systems. Digital Signal Processing (DSP) has
revolutionized modern communication and radar systems by offering unprecedented
performance and adaptivity. For broad-band systems, however, the application of
DSP is hindered by difficulty in capturing the wide-band signal. The standard
approach to deal with this problem is to employ parallelism through the use of
the time-interleaved ADC architecture. Here, the signal is captured by a
parallel array of slow digitizers. This architecture suffers from mismatches
between digitizers that limit the dynamic range and therefore limits the
resolution of such sample-interleaved ADC systems. An entirely new ADC
architecture called time-stretched ADC overcomes these issues using high speed
broadband Mach-Zehnder modulators. Here, the analog signal is slowed down prior
to sampling and quantization by an electronic digitizer in the optical domain
using the certain non-linearities in the optical fiber. This technique has
applications in ultra high frequency communication, instrumentation and radar
systems. 

"GigOptix`s unique EO polymer modulator technology is enabling a new branch of
application in ultra high speed RF photonics," commented UCLA Researcher Ali
Motafakker. "Ultra-wide-band ADC is a very challenging problem and our team is
very excited about the performance of the LX8900 device and its potential to
solve issues in this field. We are looking forward to continuing to drive this
technology forward." 

"We are very happy to see these excellent results coming back so quickly from
our collaboration with UCLA," stated Andrea Betti-Berutto, Chief Technology
Officer of GigOptix. "This is a significant moment for GigOptix in that it not
only verifies our vision of combining our broadband EO polymer modulator
technology with our broadband RF expertise and but also confirms our strategy of
collaborating with leading research groups to define new applications for our
technologies." 

LX8900 samples are available immediately. Please contact sales@gigoptix.com for
