The Broadcom® BCM53118 is a highly integrated,
cost-effective unmanaged-smart gigabit switch. The
switch design is based on the field-proven, industryleading
ROBO architecture. This device combines all
the functions of a high-speed switch system including
packet buffers, PHY transceivers, media access
controllers (MACs), address management, portbased
rate control, and a non-blocking switch fabric
into a single 65 nm CMOS device. Designed to be fully
compliant with the IEEE 802.3™ and IEEE 802.3x
specifications, including the MAC-control PAUSE
frame, the BCM53118 provides compatibility with all
industry-standard Ethernet, Fast Ethernet, and
Gigabit Ethernet (GbE) devices.
The BCM53118 has a rich feature set suitable for not
only standard GbE connectivity for desktop and
laptop PCs, but also for next-generation gaming
consoles, set-top boxes, networked DVD players, and
home theater receivers. It is also specifically
designed for next generation SOHO/SMB routers and
gateways.
The BCM53118 contains eight full-duplex 10/100/
1000BASE-TX Ethernet transceivers. In addition, the
BCM53118 has one GMII/RGMII/MII/RvMII/TMII
interface for the CPU or a router chip, providing
flexible 10/100/1000-Mbps connectivity.
The BCM53118 provides 70+ on-chip MIB counters to
collect receive and transmit statistics for each port.
The BCM53118 is available in commercial
temperature (C-Temp) rated packages. The
commercial-grade BCM53118 is provided in a 256-
pin eLQFP (28 mm × 28 mm) package.
