The BCM5703 is a highly integrated solution combining a triple-speed, IEEE 802.3 compliant media access controller (MAC), PCI and PCI-X bus interfaces, an onchip buffer memory, and an integrated physical layer transceiver in a single device. The BCM5703 is fabricated in a low-voltage, 0.13-µm CMOS process providing a low-power system solution. The BCM5703 provides a complete single-chip Gigabit Ethernet NIC or LOM solution. The BCM5703 includes a 10/100/1000-Mbps Ethernet MAC with full/ half-duplex capability at all speeds and a 10/100/1000 copper PHY. 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. The device provides both PCI v2.2 and PCI-X v1.0 bus interfaces. The BCM5703 provides a large on-chip buffer memory for stand-alone operation. Dual on-chip high-performance processors enable custom frame processing features, including TCP segmentation. The transceiver is fully compatible with the IEEE 802.3 standard for auto-negotiation of speed. Additionally, several Plug and Play enhancements have been added to make the device even more userfriendly. A link quality indicator LED gives installers an instant visual indication of any issues with the wiring plant supporting operation at the desired speed, which include 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. The BCM5703 continually monitors various channel conditions. The optional wirespeed capability allows the BCM5703 to force autonegotiation to be automatically limited by the speed that the channel can reliably support (rather than by the performance of the end equipment).
