High-Performance Ethernet ICs

Our Ethernet controllers include an integrated Ethernet MAC and PHY with a high-performance SRAM-like client interface, as well as support for external MII and PCI interfaces. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bit external bus. The controllers are also available with variable I/O voltages and multiple package options.
