BCM57765 Broadcom Corp., BCM57765 Datasheet - Page 2

• Manufacturer Part Number: BCM57765
• Description: Integrated Gigabit Ethernet And Memory Card Reader Controller
• Manufacturer: Broadcom Corp.

The BCM57765 is a Broadcom
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.

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.
Target applications:
• Desktop and mobile PC LOM and memory card reader
