BCM5787M Block Diagram
The BCM5787M is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet media access control and physical layer transceiver solution for
high-performance network applications. The BCM5787M 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
BCM5787M provides a complete single-chip Gigabit Ethernet NIC or
LOM solution.
The BCM5787M 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.
A unique integrated cable analyzer feature allows an end user to self-
diagnose any issues with the network cabling that could affect the host
machine. A link quality indicator LED and a GUI application give
installers an instant visual indication of problems. This includes physical
wiring defects or channel conditions, such as excessive cable length,
return loss, crosstalk, echo, and noise.
Broadcom's remote cable management and diagnostics software can be
used with the device to provide remote management of the cable and a
first level of diagnostics and fault isolation.
