Integrated Gigabit Ethernet and Memory Card Reader Controller
The BCM57785 is a Broadcom NetLink® highly integrated multifunction controller that integrates a single-port triple-speed 10/100/1000BASE-T Ethernet LAN controller along with a 5-in-1 memory card reader controller that supports the latest Flash™ memory cards for SD, MMC, MS, MS PRO, and xD-Picture types. 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 BCM57785 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 BCM57785 combines digital adaptive equalizers, ADCs, PLLs, line drivers, echo cancellers, crosstalk cancellers, and all other required support circuitry. A fullfeatured MAC provides full-/half-duplex capability at all speeds.
