NetXtreme® Gigabit Ethernet Controller for Servers
The BCM5723 is an eleventh-generation 10/100/1000-Mbit BASE-T Ethernet LAN controller solution for high-performance network applications. The device combines a triple-speed IEEE 802.3-compliant media access controller (MAC) with a triple-speed Ethernet transceiver, x1 PCIe™ bus interface, and on-chip buffer memory in a single device. The BCM5723 is fabricated in a 1.2V CMOS process, providing a low-power system solution.
The BCM5723 includes a 10/100/1000-Mbps Ethernet MAC with full-duplex and half-duplex capabilities at all speeds. Support for the following 802.3 functions are featured in the MAC with VLAN tagging, Layer 2 priority encoding and Full-duplex flow control. The device performs all the physical layer functions for 1000BASE-T, 100BASE-T, and 10BASE-T Ethernet on standard Category 5 UTP cable. Based on proven DSP technology, the device is a highly integrated solution combining digital adaptive equalizers, ADCs, PLLs, line drivers, echo cancellers, crosstalk cancellers and all other required support circuitry. A full-featured MAC provides full/half-duplex capability at all speeds.
