BCM53286MKPBG

Tenth-generation RoboSwitch design based on the field-proven BCM53242/BCM53262 device. This integrated 65 nm 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 nonblocking 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 all industry-standard Ethernet and Fast Ethernet devices. The BCM5328XM contains 8/16/24 full-duplex 10BASE-T/ 100BASE-TX Fast Ethernet transceivers. Each transceiver performs all 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. The BCM5328XM has two GMII/ RGMII interfaces or four SGMII/SerDes (serializer/deserializer) interfaces or two SGMII/SerDes with 2.5G combo SerDes interface. An additional MAC is included for CPU connection using an interface.

• Tenth-generation L2+ Fast Ethernet (FE) switch with the following interfaces:
  • 8-/16-/24-port 10/100 transceivers for TX/RX supporting auto power-down modes
  • 8/16/24 MAC and one MAC/GMAC for IMP
  • Two GMACs or four GMACs or two GMACs with one 2.5G MAC
  • 10 Mbit (1.25 MB) packet buffer and control memory
  • Management port with RvMII/MII or RGMII interface
• Nonblocking switch fabric
• MAC Address Learning:
  • 16K MAC addresses: automatic learning and BROng
  • 4K-entry multicast address table
  • Enable/disable MAC learning based on per-port, per-VLAN or per-packet flow (Compact Field Processor)
• Virtual Multicast Packet Replication
• 676-pin PBGA Package
