BCM5705 - 10/100/1000BASE-T Ethernet Controller with Integrated Transceiver

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

The BCM5705 is a fully integrated 10/10/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver 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.

  • Single-chip device for desktop LAN on Motherboard (LOM) or Network Interface Card (NIC) applications
  • Integrated 10/100/1000BASE-T transceiver with 10/100/1000BASE-T triple-speed MAC, PCI v2.2, 32-bit/33-MHz host interface, high-speed RISC core with 24 KB caches, SMBus 2.0 controller, and on-chip power circuit controller and Wake-on-LAN power switching circuit
  • Ultralow power for small form factor PCs with Broadcom's lowest power 0.13µ CMOS design and advanced power management
  • Enables desktop PC products for all segments -allows one board layout for both Gigabit and Fast Ethernet applications
