NetLink® Gigabit Ethernet Controller with PCI Express®
The BCM5787 is a fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5787 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 BCM5787 provides a complete single-chip Gigabit Ethernet NIC or LOM solution.
The BCM5787 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. The transceiver is fully compatible with the IEEE 802.3 standard for auto-negotiation of speed. Additionally, several plug-and-play enhancements are included to make the device even more user-friendly.
- Single-chip device for desktop LAN-on-Motherboard (LoM) or network interface card (NIC) applications
- Integrated 10/100/1000BASE-T transceiver with triple-speed MAC, high-speed RISC core with 32-KB cache, SMBus 2.0 controller, on-chip voltage regulation and Wake-on-LAN power switching circuit
- PCI Express provides wirespeed non-blocking throughput, TCP/IP stack offloads significantly reduce utilization of CPU and TCP/IP stack offloads significantly increase throughput to enable faster downloads of large files which all contribute to faster wirespeed performance and increased user performance
- Broadcom's smallest GbE form factor enables easier motherboard design with 15 x 15-mm package, 196-pin fpBGA, 10x10 mm package, 68-pin QFN and integrated WoL switching eliminates external power switching components
