(注意:这只是一个芯片的Datasheet,不喜勿下)
GENERAL DESCRIPTION
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 industrystandard
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 |
