Dual-Port 10/100/1000BASE-T PCI-X® Ethernet Controller with Integrated Transceiver
The BCM5704C is a fully integrated dual-port, 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5704C is a highly integrated solution combining two triple-speed, IEEE 802.3-compliant media access control (MAC), PCI, and PCI-X bus interfaces, an on-chip buffer memory, and an integrated physical layer transceiver in a single device. The BCM5704C is fabricated in a low-voltage, 0.13-μm CMOS process providing a low-power system solution. By itself the BCM5704C provides a complete single-chip dual-port Gigabit Ethernet NIC or LoM solution.
The BCM5704C includes two 10/100/1000-Mbps Ethernet MACs with full/half-duplex capability at all speeds and two 10/100/1000 copper PHYs. Support for the following 802.3 functions is featured in the MAC: VLAN tagging, layer 2 priority encoding, link aggregation, and fullduplex flow control.
- Single-chip, dual-port solution for dual LAN on Motherboard (LoM) and network interface card (NIC) applications
- Two integrated 10BASE-T/100BASE-TX/1000BASE-T transceivers
- Industry's smallest dual 10/100/1000 MAC/PHY solution - power and space optimized for LoM and low-profile NIC applications
- Completely backward compatible with both 10/100 network infrastructure and PCI based desktop/server platforms
