Motorola and Power over Ethernet (PoE) firm PowerDsine are developing an integrated circuit for the emerging PoE market.
PowerDsine and Motorola's semiconductor products sector will assemble a joint team of engineers to design 802.3af-compliant chips based on Motorola's SmartMOS technology and PowerDsine's Power over local area network technology.
The first chip will integrate power, analogue and logic functions into one device. Its use in Ethernet switches and midspans, an alternative for power sourcing equipment, will allow next-generation network devices to share power and data over the same cable.
"By easing the expansion of networks, PoE reduces common concerns for limited space, costly installations and extensive back-up systems," said Dave Passmore, research director of analyst firm Burton Group.
"And, as the industrial market gravitates towards Ethernet bus applications, PoE opens doors for automation and control applications."
The first product resulting from the Motorola-PowerDsine collaboration will address the needs for 12, 24 and 48-output equipment.
Unlike other semiconductors offered for PoE, the chip designed by Motorola and PowerDsine is expected to provide power to 12 Ethernet ports (15W power per port) through one chip.
