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 fullduplex and half-duplex capabilities at all speeds. Support for the following IEEE 802.3™ functions is featured in the MAC: • VLAN tagging • Layer 2 priority encoding • 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. The on-chip high-performance processor enables custom frame processing features.
