• Manufacturer Part Number: bcm53118
• Description: Bcm53118 - 9-port Gbe Switch With 8 Integrated 10/100/1000 Phys
• Manufacturer: Broadcom Corp.

The BCM53118 is a highly integrated, cost-effective, gigabit switch.
The switch design is based on the field-proven industry-leading
BCM5398. The BCM53118 combines all the functions of a high-speed
switch system, including eight full-duplex 10/100/1000BASE-T/TX
Ethernet transceivers, packet buffer, Media Access Controllers (MACs),
and a non-blocking switch fabric, into a single 65-nm LP CMOS device.
In addition, the BCM53118 has one GMII/RGMII/MII/RvMII interface
for a CPU or a wireless/DSL/cable router chip. It complies with the
IEEE 802.3™ and IEEE 802.3x specifications, including the MAC
control PAUSE frame, providing compatibility with all industry-
standard Ethernet, Fast Ethernet, and Gigabit Ethernet (GbE) devices.
The BCM53118 is packed with features, including VLAN, VLAN
double tagging, per port QoS, jumbo frame support, DOS prevent
engine, per port rate control, and MIBs management. It also includes two
Broadcom patented technologies, LoopDTech and CableChecker, that
are designed to lower the human effort for troubleshooting cable
problems and loops during installation and for post-installation support.

LoopDTech also eliminates the additional cost of hardware and software
required to run Spanning Tree Protocol. CableChecker, unlike traditional
TDR-based cable diagnostics, can detect cable and connector problems
without disconnecting the cable from the other end. This allows
CableChecker to run while the switch is passing packets. Network
support personnel can monitor and troubleshoot network problems
remotely, which is very important in an SMB environment, where IT
resources are scarce. LoopDTech and CableChecker, when set up
correctly, actually detect problems automatically without any human
intervention.
The BCM53118 has all the features required to enable residential
gateways and home office switches that can be connected to voice,
multimedia, and data devices simultaneously. With per-port QoS/
queuing and rate control support, different packet types can be identified
and prioritized within the switch, and voice packets can be assigned a
higher priority for outbound delivery.
