F E A T U R E S

Eighth-generation switch on a chip

Integrates

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.

•

One GMII/RGMII/RvMII interface

Seventeen MACs (802.x compliant) with support for 9-KB

jumbo frames

•

Sixteen SGMII/SerDes interfaces and 256-KB packet buffer

memory

Non-blocking 17-Gigabit Ethernet fully integrated switch fabric

SPI Interface for easy setup and managed operation

Provides the most cost-effective Gigabit Ethernet connectivity

to the desktop and control plane for all remote, branch, and

Enterprise needs.

•

802.1Q tag VLAN, trunking, and 802.1p priority enables the

switch to be designed into a wide variety of applications from

unmanaged to websmart to managed switch.

Classifies packets using four 802.1p QoS or DiffServ priority

queues

•

Jumbo frame support allows the device to be connected to

corporate server farms and networks while maintaining

maximum TCP/IP performance.

VLAN 4k 802.1Q or port-based support

Supports up to 4k unicast MAC addresses

Supports MAC-based port aggregation (trunking)

Flow control

•

CPUs are not required to initialize and run in cost-sensitive

unmanaged applications, providing true plug-and-play

connectivity.

•

Full-duplex (802.3x) and half-duplex options support

Suitable for fully managed applications due to support for

Spanning Tree and 802.1x MAC security

•

Supports automatic address learning and aging

Support for Spanning Tree and Rapid Spanning Tree

Low power 0.13 µm 1.2 V CMOS core: <2.5W Pd.

Supports 802.1x MAC Security

•

SGMII interfaces ensure superior EMI performance and

lowest possible number of required board layers while

enabling connections to industry-standard physical layer

devices (e.g., BCM5464R)

Port-based rate control feature with 64kbps granularity

256-pin FBGA package (small form factor 17 mm x 17 mm)

Lowest possible system cost through minimized number of

external components.

•

Higher system reliability and noise reduction due to

elimination of component with lowest MTBF (the fan).

BCM5396 Block Diagram

The Broadcom BCM5396 device is a 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, SerDes, media

access controllers, address management, and a nonblocking switch

fabric into a single 0.13 µm CMOS device.

typically used for high-performance connections to servers because they

offer a smaller percentage of overhead on the link for more efficiency.

SPI or EEPROM interfaces provide easy programming of the on-chip

802.1p QoS and/or DiffServ. This allows switch traffic to be given

different classes of priority or service. For example, voice traffic for IP

phone applications, video traffic for multimedia applications, or data

traffic for e-mail applications. Up to 4k virtual LANs (VLANs) can be

set up via the SPI port for separation of different users or groups on the

network. For multi-Gigabit per second connections, multiple ports of the

BCM5389 can be grouped together to form logical links. These links

feature automatic load balancing.

The BCM5396 complies with 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 Gigabit Ethernet devices.

The integrated sixteen SerDes cores enable direct connections across

backplanes with the lowest possible amount of traces. The device also

integrates seventeen IEEE compliant 10/100/1000 MACs. Sixteen of

these are internally connected to the SerDes cores offering alternatively

true serial interfaces for backplane connections or fiber optic

The BCM5396 can also be used in fully managed applications where

support for Spanning Tree and 802.1x MAC security are a requirement.

In such applications, the CPU will be connected using the SPI interface

for register control and the ninth MII interface for protocol frames.

transceivers or SGMII interfaces for connection to industry-standard

Gigabit Ethernet copper transceivers such as the Broadcom BCM5464R.

The seventeenth MAC features multiple MII interface modes (RvMII,

RGMII, GMII) for connection to a variety of CPUs.The media access

controllers on the BCM5396 also support jumbo frames which are

Finally, the BCM5396 supports per-port rate control for applications like

MTU/MDU switches where individual ports need to be restricted in

speed to comply with the agreed and paid for service levels.
