The device combines a triple-speed IEEE 802.3™-compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, x1 PCIe bus interface, memory card interface controller, and on-chip buffer memory in a single device. The BCM57765 is fabricated using 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 BCM57765 combines digital adaptive equalizers, ADCs, PLLs, line drivers, echo cancellers, crosstalk cancellers, and all other required support circuitry. A fullfeatured MAC provides full-duplex/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 BCM57765 integrates on-chip switching regulators and nonvolatile memory that eliminates the need for an external NVRAM device. The BCM57765 is truly a single-chip solution for Gigabit Ethernet LOM and 5-in-1 memory card reader packaged in a small 68-pin QFN package.
