LAS VEGAS -- During the Networld+Interop trade show here, Marvell Semiconductor Inc. and Galileo Technology Ltd. here today said a partnership between the two companies has resulted in a new design reference platform for Gigabit Ethernet data transmissions over copper-wire networks. The design uses a new 0.18-micron transceiver chip from Marvell and a Gigabit Ethernet switch controller from Galileo.
The partnership is intended to accelerate development of Gigabit Ethernet systems using Marvell's new Alaska copper transceiver. "Our Alaska Gigabit Ethernet PHY Physical Layer device coupled with Galileo's Gigabit Ethernet switch will provide our customers with higher port density and quicker time-to-market solutions," asserted Weili Dai, executive vice president and general manager for Marvell's Data Communications Group, based in Sunnyvale, Calif.
According to Marvell, the Alaska transceiver is designed to enable suppliers of enterprise switch/router systems to increase the number of Gigabit Ethernet ports in equipment by two to three times. The transceiver is also being introduced by Marvell at the Las Vegas show this week. It is packaged in a 128-pin plastic QFP and priced at $56 each in sample quantities.
"The low power, small footprint Alaska device enabled by Marvell's advanced DSP digital signal processing technology is in line with our strategy to accelerate the emergence of Gigabit Ethernet in the networking market," said Moshe Steiner, Galileo's vice president and general manager of switchingproducts, based in San Jose.
Marvell said its Alaska Gigabit Ethernet transceiver incorporates all three Ethernet speeds (10, 100, and 1,000 megabit per second) with standards-based auto-negotiation to assure compatibility with all existing Ethernet networks. The design uses mixed-signal and DSP circuits as well as power management techniques to lower power dissipation to 1.8 watts vs. 7 watts for existing single-port Gigabit-over-copper transceivers, according to the Sunnyvale company.
