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

The BCM5755 is a fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5755 combines a triple-speed, IEEE 802.3-compliant media access controller (MAC), PCI Express bus interface, on-chip buffer memory, and integrated physical layer transceiver in a single device. It is fabricated in a low-voltage silicon process providing an ultra-low power solution. By itself, the BCM5755 provides a complete single-chip Gigabit Ethernet LAN-on-Motherboard (LOM) solution.

The BCM5755 includes a 10/100/1000-Mbps Ethernet MAC with full/half-duplex capability at all speeds. Support for the following 802.3 functions is featured in the MAC: VLAN tagging, layer 2 priority encoding, and full-duplex flow control.
