The BCM5721 is a fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5721 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.
The BCM5721 is fabricated in a low voltage silicon process, providing an ultra-low power solution. By itself, the BCM5721 provides a complete single-chip Gigabit Ethernet NIC or LOM solution. The BCM5721 includes a 10/100/1000-Mbps Ethernet MAC with fullduplex and half-duplex capability at all speeds. Support for the following 802.3 functions is featured in the MAC:
• VLAN tagging
• Layer 2 priority encoding
• 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 a 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.
