BCM5700 10/100/1000 PCI-X NIC Reference Design B C M 5 7 0 0 O V E R V I E W MHz The BCM5700 is a high-performance 10/100/1000BASE-T Ethernet LAN controller optimized for NIC and LOM applications. The BCM5700 is a highly integrated solution combining 10/100/1000BASE-T IEEE 802.3 compliant Media Access Controller (MAC), PCI and PCI-X bus interfaces, and on-chip buffer memory in a single device. The BCM5700 is fabricated in a low voltage 1.8V CMOS process, providing a low power system solution. Combine the BCM5700 with the BCM5401 (or later) single-chip Gigabit Ethernet Transceiver to achieve a complete NIC or LOM solution for 10/100/1000BASE-T Ethernet. The BCM5700 includes a 10/100/1000 Mbps Ethernet MAC with full/half-duplex capability at all speeds. The MAC interfaces to the external transciever via the GMII in 1000BASE-T mode, the MII in 10/100BASE-T mode, and TBI serial interface in 1000BASE-SX/1000BASE-FX mode. Support for the following 802.3 packet tagging functions is featured in the MAC: VLAN tagging, Layer 2 priority encoding, link aggregation, and fullduplex flow control. The device provides both PCI v2.2 32/64-Bit, 33/66 MHz, and PCI-X v1.0, 133 MHz, host interfaces. The BCM5700 includes a 96 KB on-chip buffer memory for stand-alone operation, and optionally supports up to 16 MB of external memory. Dual onchip high-performance processors enable many custom frame processing features, including TCP segmentation. Target Applications of the BCM5700 BCM5700 Operating System * Microsoft Windows NT 4.0 * Microsoft Windows 2000 * Linux 2.2 * NetWare 4.11, 4.2 and 5.x Broadcom(R) and the pulse logo are registered trademarks of Broadcom Corporation and/or its subsidiaries in the United States and certain other countries.
