Acelo Semiconductor Launches Company - Introduces Its GaAs PHEMT Technology Solution for Fiber Optic and Broadband Wireless Communications Markets

GaAs PHEMT Technology Meets the Demand for Analog Integrated Circuits Operating at 40 Gb/s

Oxnard, CA. Acelo Semiconductor Inc.™, creator of semiconductor solutions that accelerate the gateways across fiber optic networks, today officially announced its launch, signaling the emergence of a provider of a new level of performance, reliability and speed to support the most effective transfer of data and information.

Acelo s current product line includes OC192 and OC768 analog chipset solutions that provide industry-leading performance in tackling some of the most difficult challenges faced by telecommunications equipment makers in the core and metro applications. The company holds an exclusive license covering PHEMT technology from Rockwell Scientific. Investors in Acelo include Rockwell Scientific, Cisco and Parakletos@Ventures.

"Fiber optics form the backbone of broadband telecommunication systems. As single channel data rates increase from 10 Gb/s to 40 Gb/s, it presents a significant challenge to the chip technology, especially for difficult functions such as modulator drivers and trans-impedance amplifiers," said Derek Cheung, president & CEO at Rockwell Scientific. "With its in-house PHEMT fab technology and innovative design expertise, Acelo is the only company that offers a solution to such requirements while meeting the performance and reliability criteria. This accomplishment has put Acelo in a strong and unique position to address this growing market."

Leveraging its exclusive license from Rockwell Scientific, Acelo designs, develops, manufactures and markets GaAs PHEMT-based integrated circuits, to later include other leading integrated circuit technologies. Key considerations for the analog chips in SONET transponders are switching speed, power dissipation and breakdown voltage, Acelo is committed to developing products that exceed the necessary chip requirements. The GaAs PHEMT technology provides the necessary performance elements required for OC192 and OC768 analog applications while offering a maturity level that directly addresses manufacturing and reliability concerns.

Acelo s products in fiber optic telecommunications include modulator/laser drivers and transimpedance amplifiers for the 10Gb/s and 40Gb/s systems (OC192, OC768), each with significant product advantages. As an example, the OC192 laser driver solution offers several benefits: the lowest power dissipation of 800-900mW at full-drive current -- which enables greater reliability and ease of packaging, a distinctively small size, which is critical for competitive modules -- and high gain/low noise which results in higher sensitivity. In addition, Acelo s OC768 modulator driver solution is currently the only single chip solution that is capable of driving Lithium Niobate modulators. For the broadband wireless market, Acelo offers power and low noise amplifiers for the point to point and point to multipoint distribution systems operating at 30+ GHz.

"We strongly believe that the ability to design and manufacture high performance PHEMT integrated circuits is the basis upon which high-value circuit designs can be translated quickly and efficiently to market-leading products," said John Hong, Acelo s CEO, who spent 13 years with Rockwell Scientific, most recently as director of Electronics. "Having all design and fabrication in-house for 10 Gb/s and 40 Gb/s modulator drivers and transimpedance amplifiers, including wafer processing, allows us to best apply a customized approach and deliver immediate solutions to telecommunications equipment makers."

As a July 9 Gartner analyst report attests, fiber-optic and wireless communications continue to demand greater performance from the semiconductor technologies that are essential to the continued growth of these industries. The report continues that the emerging market for fixed broadband wireless access demands products that can operate in the range of 30GHz/a. Currently, five of Acelo s seven products are sampling at both the OC192 and OC768 data rates. Acelo is currently sampling the following products:

  • OC192 Laser Driver
  • Low power: Laser driver dissipates 800-900mW at full output current
  • Small size (1.0 X 1.1) mm
  • OC192 Modulator Driver
  • High output voltage swing is 7.5 Vpp (with 26dB gain) @ 1.4W chip dissipation
  • OC192 High Gain TIA
  • High TZ gain of 10K ohms with limiting output
  • OC768 Modulator Driver
  • High output voltage swing is 8Vpp (with 17dB gain) @ 800 mW
  • Wideband operation ranges from 100 KHz-50GHz (3dB pts.)
  • OC768 TIA
  • High TZ gain of 400-800 ohms Acelo is developing mixed signal integrated circuit technologies for OC768 to complete its chipset offering for OC768 transponders. These products will be available in early 2002.
