MILPITAS, Calif. --LSI Logic Corp. today announced availability of the industry's first Fast Ethernet octal media access controller (MAC) and physical layer device (PHY) on a chip. The octal MAC/PHY combo chip, called L88800, is aimed at high-speed networking applications, such as Ethernet switches, backbones, network convergence, and network processors, said the company.
"The integrated MAC and PHY--coupled with the flexible split bus interface and smaller die size--offer enormous competitive advantages, reducing both design time and cost," said Majid Bemanian, director of marketing for LSI Logic's Networking Products Division.
According to LSI Logic, the L88800 is the first device of its kind to integrate eight physical layer devices and eight media access controllers on a single die. The integration reduces pin count and eliminates problems associated with simultaneous switching outputs, said Milpitas-based LSI Logic. Each port contains an IEEE 802.3u compliant Ethernet MAC and a complete IEEE compliant 10/100 megabit-per-second Ethernet PHY that can be configured for either 100 Mbit/sec. (100BaseFX or 100BaseTX) or 10 Mbit/sec. (10BaseT) Ethernet operation.
Working at full capacity, the L88800 can handle up to 4.8 gigabits per second of data from all eight ports at the same time, said LSI Logic. This capability will allow up to 24 full-duplex ports to be configured on the same bus.
Available is sample quantities now, the L88800 is priced at $40.50 each in quantities of 50,000. Volume production is slated to begin later this fall.
