Description

The BCM5705 is a fully integrated 10/10/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver BCM5705 solution for high-performance network applications. The BCM5705 combines a triple-speed, IEEE 802.3™ compliant Media Access Controller (MAC), a PCI bus interface, an on-chip buffer memory, and an integrated physical layer transceiver in a single device. The BCM5705 is fabricated in a low-voltage 0.13µ CMOS process, providing an ultralow power solution. By itself, the BCM5705 provides a complete single-chip Gigabit Ethernet NIC or LOM solution.

The BCM5705 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, link aggregation and full-duplex flow control.
