®
BCM53106P is an ultra low-power, highly
integrated, cost-effective smart-managed Fast Ethernet
switch. The switch design is based on the field-proven,
industry-leading 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, port-based rate control,
and a nonblocking switch fabric into a single 28 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 BCM53106P provides compatibility with
all industry-standard Ethernet and Fast Ethernet devices.
The BCM53106P has a rich feature set suitable for not only
standard Fast Ethernet connectivity for broadband home
gateways, 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 BCM53106P contains four full-duplex 10/100BASE-TX
Ethernet transceivers. In addition, the BCM53106P has two
PHY-less interfaces for the CPU or a router chip, providing
flexible 10/100 Mbps connectivity. One RGMII interface can
be connected to a CPU entity and configured as an IMP (In
Band Management port).
The second interface port is available in an SGMII interface
supporting rates of up to 2.5 Gb/s that can be connected to
optical modules or any other device with an SGMII
interface.
The BCM53106P provides 70+ on-chip MIB counters to
collect receive and transmit statistics for each port.
The BCM53106P is available in industrial temperature (I-
Temp) and commercial temperature (C-Temp) rated
packages. The BCM53106P is available in one package
type, a 212-pin FBGA package.
