• Manufacturer Part Number: bcm57761
• Description: Integrated Gigabit Ethernet Controller
• Manufacturer: Broadcom Corp.

The BCM57761 is a Broadcom
10/100/1000BASE-T Ethernet LAN controller solution for high-
performance network applications. The device combines a triple-speed
IEEE 802.3™-compliant MAC with a triple-speed Ethernet transceiver,
x1 PCIe bus interface, and on-chip buffer memory in a single device. The
BCM57761 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 BCM57761 integrates on-chip
switching regulators and nonvolatile memory that eliminates the need for
an external NVRAM device. The BCM57761 is truly a single-chip
solution for a Gigabit Ethernet (GbE) LOM.
