BCM57765

NetXtreme® Gigabit Ethernet Controller with Integrated SDXC Card Reader, ASF and EEE Compliant

The BCM57765 is a Broadcom NetXtreme® 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 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 full-featured MAC provides full-duplex/half-duplex capability at all speeds.
