Microsemi Extending Its PowerDsine PoE Midspan Applications to Hi-Rel Markets


IRVINE, Calif., June 26, 2007 (PRIME NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, has announced that it is aggressively pursuing applications in high-reliability aerospace/defense, commercial air and national security markets for its recently acquired PowerDsine(r) Power over Ethernet (PoE) midspan product line.

"These are largely untapped markets for our new midspan products," said James J. Peterson, Microsemi President and CEO. "Prior to the acquisition, PowerDsine focused largely on commercial installations. Adding Microsemi's deep experience in high-reliability markets, we now can deliver PoE technology to a far wider audience. For example, we envision many high-reliability applications to spin off from the wide commercial use of our PoE technology for powering security cameras," Peterson said.

Punctuating early success in this new initiative, Microsemi announced that it has received its first high-reliability order for 5,000 PowerDsine single-port midspans from AirDefense, Inc., of Alpharetta, Georgia.

"In addition, our recently released high power chipset family provided the industry with its first pre-standard IEEE802.3at integrated solution able to deliver up to 60 watts of power for end devices like pan-tilt-zoom and dome cameras, video screen phones, WiMAX transmitters, thin-clients and laptop computers. This new standard, and our continuing development of PoE solutions, can extend our reach for both commercial and high reliability applications -- establishing Microsemi as the leading provider to these expansive markets," Peterson added.

PowerDsine engineers pioneered PoE technology, were a driving force for the existing standards, and are heavily involved in the creation of the soon-to-be released IEEE802.3at standards for next-generation higher power midspans.
