Single-Chip 16-Port SerDes Gigabit Switch
GENERAL DESCRIPTION
FEATURES
The BCM5396 is a 16-port Gigabit Ethernet (GbE)
switch integrated with 16 1.25G SerDes/SGMII port
interfaces for connecting to external Gigabit PHYs or
fiber modules. The BCM5396 provides the lowest-
cost GbE functionality to the desktop switching
solution or WebSmart™ application.
The BCM5396 is a highly integrated solution,
combining all of the functions of a high-speed switch
system, including packet buffer, Media Access
Controllers (MACs), address management, and a non-
blocking switch controller into a single monolithic
0.13 µm CMOS device. The BCM5396 complies with
the IEEE 802.3™, 802.3u, 802.3ab, and 802.3x
specifications, including the MAC control PAUSE
frame and auto-negotiation subsections, providing
compatibility with all industry-standard Ethernet,
Fast Ethernet, and GbE devices.
The BCM5396 device provides integrated 1.25G
SerDes, reducing board footprint requirements. The
16 ports have SGMII interfaces for connecting with
external GbE transceivers.
