BCM5325

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

The Broadcom BCM5325 device is a highly integrated solution. It combines all of the functions of a high-speed switch system -including packet buffer, PHY transceivers, media access controllers, address management, and a nonblocking switch fabric -into a single 0.18μ CMOS device. It complies with the IEEE 802.3, 802.3μ, and 802.3x specifications, including the MAC control PAUSE frame and auto-negotiation subsections, providing compatibility with all industry-standard Ethernet and Fast Ethernet devices.

This device 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.

  • The highest level of silicon integration achieved for a five-port 10/100 Ethernet switch device
  • Fourth generation switch on a chip
  • Enables a new generation of lower cost 10/100 switches in much smaller form factors
  • Utilizes field-proven industry-standard 10BASE T/100BASETX Fast Ethernet transceivers -lowering overall system interoperability and reliability risks
