The device combines dual triple-speed IEEE 802.3-compliant Media Access Controllers (MACs) with dual 10/100/1000 Ethernet Transceivers, a Universal Management Port (UMP), and an on-chip memory buffer in a single device. The device is fabricated in a 1.2V CMOS process, providing a low-power system solution. The BCM5715C provides a single x4 PCI Express host interface and two Gigabit Ethernet Controllers. Each function has its own PCI configuration space. Each Ethernet controller has a dedicated on-chip high-performance RISC processor for custom frame features. The BCM5715C supports a Universal Management Port (UMP) interface for high-speed system management communications via the dual Gigabit Ethernet ports. The BCM5715C performs all physical layer functions for 1000BASE-T, 100BASE-T, and 10BASE-T 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 cancelers, crosstalk cancellers, and all other required support circuitry. Two full-featured MACs provide full-duplex and half-duplex modes at 1000 Mbps.
