Integrated 10/100BASE-T/TX 5/6-Port Managed Switch

The BCM5325E is the feature-enhanced and pin-compatible six-port switch to the industry leader BCM5325M 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 single 0.18-μm CMOS device. The BCM5325E complies with the IEEE 802.3, 802.3u, and 802.3x specifications, including the MAC control PAUSE frame and autonegotiation subsections, providing compatibility with all industrystandard Ethernet and Fast Ethernet devices.

The BCM5325E contains five full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers, each of which 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.

  • High level of integration with five transceivers (802.3u compliant) and six Media Access Controllers (MACs) (802.3x compliant)
  • 802.1p QoS packet classification with four priority queues
  • Enables a new generation of affordable five-port 10/100 switches with highest integration of enhanced L2+ features
  • Utilizes field-proven industry-standard 10BASE-T/100BASETX (100BASE-FX-compatible) Fast Ethernet transceivers -lowering overall system interoperability and reliability risks
