5-GbE Port Switch with Integrated SerDes

Currently Viewing:

Highly integrated solution ideally suited for standalone Gigabit Ethernet switches and Gigabit Ethernet control plane and backplane applications.
It combines all the functions of a high-speed switch system — including packet buffer, serializer/deserializer (SerDes), media access controllers, address management and a nonblocking switch fabric — into a single 0.13-micron CMOS device. The BCM5387 complies with IEEE 802.3, 802.3u, 802.3ab and 802.3x specifications, including the MAC control, pause frame and autonegotiation subsections, providing compatibility with all industry-standard Ethernet, Fast Ethernet and Gigabit Ethernet devices.

  • Low-power 0.13-micron 1.2 V CMOS core: <1.5W Pd.
  • Eighth-generation switch on a chip
  • Enables a new generation of lower-cost switches with Gigabit Ethernet connectivity and much smaller form factors
  • Uses field-proven industry-standard Gigabit Ethernet SerDes, which lowers overall system interoperability and reliability risks.
