LAS VEGAS--At the Networld+Interop trade show here, LSI Logic Corp. took the wraps off a new "mini" ball-grid array package for Gigabit Ethernet controllers that's 70% smaller than existing 208-pin plastic packages used to house the function, according to the Milpitas, Calif., company.
The 208-ball mini-BGA reduces the board space requirements for LSI Logic's L8104 Gigabit Ethernet Media Access Controller (MAC) device. "This new package will provide our customers with expanded design capabilities and the same leading gigabit technology they have come to relay on from LSI Logic," said Majid Bemanian, director of marketing for the company's Networking Product Division.
According to LSI Logic, the migration from existing 208-pin ball plastic quad flat pack (PQFP) to the 208 mini-BGA increases signal integrity and eases manufacturing of multi-port gigabit switches.
The L8104 integrates the MAC sublayer and the physical coding sublayer for fiber and short-haul copper network cabling. The device consists of a full duplex Ethernet MAC, receive/transmit FIFO's, 64-bit split bus system interface, 10-bit PHY interface, and a 16-bit register interface. It also contains all thenecessary circuitry to implement the flow control algorithm defined by IEEE 802.3x specification, according to LSI Logic.
The new mini-BGA L8104 will cost $35 each in 1,000-piece quantities.
