BCM5700 - 10/100/1000BASE-T PCI-X® Ethernet Controller

10/100/1000BASE-T PCI-X® Ethernet Controller

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 10/100/100BASE-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 Full-Duplex Flow Control.

  • 10/100/1000BASE-T full/half-duplex MAC with wire speed performance at all speeds
  • Support for PCI v2.2 32/64-Bit, 33/66 Mhz and PCI-X v1.0 32/64-bit, 66/133 Mhz bus interface standards
  • Integrated on-chip memory and dual, on-board RISC processors
