Optichron Reduces Nonlinear
Distortion 90 Percent - New Module Includes Linearizer Technology
Optichron Inc. a fabless semiconductor company, which just this March received $17 million
in Series B venture capital funding, has introduced its first products that incorporate its advanced nonlinear signal processing
technology, called Turbolinear. The company states that Turbolinear reduces nonlinear distortion by more than 90 percent in
high-speed piplelined data converters.
The Turbolinear technology is now available in the company's analog
to digital converter modules for applications such as multi-channel / multi-mode receivers, base stations and medical imaging
equipment. Specifications for one of the modules, the M1400A-105 ADC module, which incorporates Optichron's Linearizer integrated
circuit along with an AD6645 ADC and AD8351 amplifier, include a Signal-to-Noise Ratio (SNR) of 70 dB and a Spurious Free
Dynamic Range (SFDR) of 90 dB. Both specifications are based on an input frequency of 150 MHz. Volume production of the 105
is expected in the fourth quarter of 2005.
Roy Batruni, CEO of Optichron noted the cost significance of the
encapsulated achievement, "Optichron's Turbolinear technology is the first of its kind to transform nonlinear signal processing
from the realm of pure science into a practical engineering language uniquely suited to address the pervasive problem of nonlinear
distortion. Turbolinear technology allows engineers to utilize versatile filter architectures that eliminate nonlinear distortion
in a way that is both cost-effective and easy to implement in low-power semiconductor products."
