10/100/1000BASE-T Ethernet Controller with Integrated Transceiver

The BCM5705M is a fully integrated 10/100/1000BASE-T Gigabit Ethernet Media Access Control and Physical Layer Transceiver solution for high-performance network applications. The BCM5705M combines triple-speed, IEEE 802.3 compliant media access controller (MAC), PCI bus interface, on-chip buffer memory, and integrated physical layer transceiver in a single device. It is fabricated in a low-voltage 0.13 µm CMOS process, providing an ultra-low power solution. By itself the BCM5705M provides a complete single-chip Gigabit Ethernet NIC or LOM solution.

The BCM5705M includes a 10/100/1000-Mbps Ethernet MAC with full/half-duplex capability at all speed. Support for the following 802.3 functions is featured in the MAC: VLAN tagging, layer 2 priority encoding, and full-duplex flow control.
