General Description

The Broadcom® BCM53134M is an ultra low-power, highly integrated, cost-effective smart-managed 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, port-based rate control, and 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 BCM53134M provides compatibility with all industry-standard Ethernet, Fast Ethernet, and Gigabit Ethernet (GbE) devices.

The BCM53134M has a rich feature set suitable for not only standard GbE 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 BCM53134M contains four full-duplex 10/100/1000BASE-T Ethernet transceivers. In addition, the BCM53134M has two PHY-less interfaces for the CPU or a router chip, providing flexible 10/100/1000 Mb/s connectivity. One RGMII interface can be connected to a CPU entity and configured as an IMP (In-Band Management port).

The second RGMII interface is available for another PHY, modem, or CPU connection.

The BCM53134M provides 70+ on-chip MIB counters to collect receive and transmit statistics for each port.
