BCM53101 Block Diagram
Optimized for L2 switching, the BCM53101 is a feature-enhanced
seven-port switch to the industry-leading BCM5325E RoboSwitch™.
This device combines all the functions of a high-speed switch system,
including packet buffers, PHY transceivers, MACs, address
management, and a non-blocking switch fabric, into a 65 nm LP process.
The BCM53101 contains five full-duplex 10BASE-T/100BASE-TX
Fast Ethernet transceivers connected to the five on-chip 10/100 MACs.
In addition, a sixth 10/100 MAC is available through the MII/RvMII
interface. The BCM53101 also features a 10/100/1000 MAC, which can
be used to connect to an external CPU via the RGMII/MII/RvMII
interface.
The BCM53101 also integrates several gigabit-class features such as 4K-
entry VLAN, 2K-entry MAC addresses, ingress rate limiting and egress
rate shaping, port mirroring, IGMP/MLD snooping, and trap reserved
MAC addresses to CPU, among others.
The BCM53101 is designed from the ground up for lower power
consumption. The power-efficient on-chip PHYs help lower power
consumption by over 50% compared to its predecessor, the BCM5325E.
Fabricated using 65 nm LP process, the device consumes less than 0.7W.
Additionally, the BCM53101 incorporates several green modes such as
auto-power down, sleep mode, and a deep sleep mode (needs external
CPU).
