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 BCM57781 is fabricated in a 65 nm CMOS process, providing a low-power system solution. 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. For a lower total solution cost and lower-power system-level power consumption, the BCM57781 integrates on-chip switching regulators and nonvolatile memory that eliminates the need for external NVRAM device. The BCM57781 is truly a single-chip solution for a Gigabit-Ethernet LOM.
