BCM53202M Block Diagram
The BCM53202M is a ninth generation RoboSwitch™ design based on
the field-proven BCM5320 device. This integrated 0.13µ-CMOS device
combines all the functions of a high speed switch system including
packet buffers, PHY transceivers, Media Access Controllers (MACs),
address management, and a non-blocking switch fabric. It is designed to
be fully compliant with the IEEE 802.3 and IEEE 802.3x specifications,
including the MAC control PAUSE frame, auto-negotiation and with all
industry standard Ethernet and fast Ethernet devices.
The BCM53202M contains 8 full-duplex 10BASE-T/ 100BASE-TX fast
Ethernet transceivers with advanced cable diagnostics support. Each
performs all of the physical layer interface functions for 10BASE-T
Ethernet on Category 3, 4, or 5 Unshielded Twisted Pair (UTP) cable and
100BASE-TX fast Ethernet on category 5 UTP cable. In addition, the
BCM53202M has two GMII/RGMII/TBI interfaces that provide flexible
10/100/1000BASE-TX/FX connectivity. An additional MAC is
included for CPU connection via RvMII, or MII interface.
The BCM53202M has a rich feature set suitable for streaming VoIP,
video, and data traffic for multimedia applications. The BCM53202M
supports up to four QoS queues per port. Traffic QoS can be assigned
based on Port-ID, MAC address, 802.1p or DiffServ. Together with 4K
entries, 802.1Q VLAN, 802.1x EAPOL protocol filtering, MAC-based
link aggregation with dynamic failover, per-port bandwidth/rate control,
MAC address locking, and IGMP/MLD snooping at layer 3 allow system
vendors to build advanced L2+ switch systems for the Multi-Tenant/
Multi-Dweller Unit (MTU/MDU) markets.The BCM53202M provides
70+ on-chip MIB counters to collect receive and transmit statistics for
each port.
