• Manufacturer Part Number: bcm5757
• Description: Bcm5757 - Netxtreme Gigabit Ethernet Controller With Dash Manageability Support
• Manufacturer: Broadcom Corp.

The BCM5757 is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet media access control and physical layer transceiver solution for
high-performance network applications. The BCM5757 combines a
triple-speed, IEEE 802.3 compliant media access controller (MAC), PCI
Express bus interface, on-chip buffer memory, and integrated physical
layer transceiver in a single device. The BCM5757 is fabricated in a low-
voltage silicon process, providing an ultra-low power solution. By itself,
the BCM5757 provides a complete single-chip Gigabit Ethernet NIC or
LOM solution.
The BCM5757 includes a 10/100/1000-Mbps Ethernet MAC with full-
duplex and half-duplex capability at all speeds. Support for the following
802.3 functions is featured in the MAC—VLAN tagging, Layer 2
priority encoding, and full-duplex flow control.
The transceiver is fully compatible with the IEEE 802.3 standard for
auto-negotiation of speed. Additionally, several Plug-and-Play
enhancements are included to make the device even more user-friendly.
A unique integrated cable analyzer feature allows a user to self-diagnose
any issues with the network cabling that could affect the host machine.
A link quality indicator LED and a GUI application give installers an
instant visual indication of problems. This includes physical wiring

defects or channel conditions, such as excessive cable length, return loss,
crosstalk, echo, and noise.
Broadcom’s remote cable management and diagnostics software can be
used with the device to provide remote management of the cable and a
first level of diagnostics and fault isolation.
When combined with the BCM5758 applications processor, the
BCM5757 offers a complete hardware, firmware, and software solution
enabling DASH management functionality. The on-chip processor, and
via the SMBus controller, allows the device to communicate
management commands/responses to/from the application processor, the
system chipset and the system sensors. Providing this management
functionality as part of the Gigabit-Ethernet controller, and using a
centralized architecture, enables system vendors to offer advanced
management functionality with an extremely reliable and power efficient
solution.
