BCM5396IFB Présentation
An Ethernet switch is a semiconductor that receives Ethernet frames on multiple ports, stores them briefly, examines addressing information, and forwards each frame only toward its destination port. The BCM5396 combines physical-layer SerDes interfaces, Media Access Controllers, address management, packet buffering, and switching control within one monolithic 0.13 µm CMOS device. This integration reduces the component count required for multiport Gigabit networking equipment.
The verified BCM5396 data identifies sixteen SGMII/SerDes ports, seventeen compliant MACs, one GMII/RGMII/RvMII interface, and a non-blocking 17-Gigabit Ethernet switch fabric. It supports jumbo frames up to 9 KB and includes a 256-KB packet buffer. The Broadcom datasheet also states compliance with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, including MAC-control PAUSE handling.
Technical implementation centers on the integrated SerDes interfaces and the internal switching architecture. Sixteen Gigabit Ethernet links terminate through SGMII/SerDes, while a separate parallel interface supports an uplink or management-facing port. The switch fabric is designed to forward traffic without a blocking bottleneck across the aggregate 17-Gigabit capacity, and packet buffering absorbs short traffic bursts before forwarding decisions are completed.
Typical applications include 16-port Gigabit Ethernet switches, industrial network equipment, network-interface appliances, aggregation equipment, and embedded systems requiring multiple copper or fiber-linked Ethernet ports. The parallel uplink can connect the switched ports to a host processor, another switch, or a router, depending on the surrounding system architecture.
PCB design must follow the manufacturer’s BGA land pattern, ball assignment, power, clock, SerDes, and decoupling requirements. Differential high-speed pairs need controlled impedance, uninterrupted reference planes, minimized stubs, and manufacturer-recommended spacing. Because the supplied excerpts do not include operating voltage, temperature range, pin list, or exact package dimensions, those values should be confirmed from the full manufacturer datasheet before release.
This product record combines verified source links, procurement fields, interface facts, and design-focused context. The alternatives list remains intentionally limited because the supplied cross-reference search did not identify any verified pin-compatible replacement MPNs.

Applications typiques
BCM5396IFB convient pour 6 applications: 16-Port Gigabit Ethernet Switch, Industrial Network Aggregation, Network Interface Appliance, Embedded Control-System Gateway, Telecom Ethernet Edge Equipment, Video Network Aggregation.
16-Port Gigabit Ethernet Switch
BCM5396IFB fits a centralized 16-port Gigabit Ethernet switch because it combines sixteen SGMII/SerDes interfaces with a non-blocking 17-Gigabit switching fabric. Seventeen compliant MACs support the switched ports and uplink requirements, while the parallel GMII/RGMII/RvMII interface can connect the design to another switch or host subsystem. The 256-KB packet buffer absorbs short bursts, and support for frames up to 9 KB is useful when all attached nodes use jumbo frames. The main layout concern is routing sixteen high-speed differential SerDes lanes through the BGA package and multilayer PCB without impedance discontinuities.
Recommandé
Industrial Network Aggregation
BCM5396IFB can aggregate sixteen Gigabit Ethernet links in industrial equipment that must concentrate cameras, controllers, sensors, or service nodes into a higher-capacity uplink. The 17-Gigabit non-blocking fabric and IEEE 802.3x PAUSE support help manage congestion among the integrated ports, while the uplink interface provides a defined path toward a host or routing block. Although the topology fits industrial networking, the supplied excerpts do not confirm an industrial temperature grade, certifications, or vibration ratings; those requirements must be verified before deployment in machinery or harsh environments.
Recommandé
Network Interface Appliance
BCM5396IFB is appropriate for a network interface appliance that must terminate many Gigabit Ethernet links while coordinating traffic internally. Its integrated switch controller, Media Access Controllers, address management, and packet buffer reduce the component count associated with a discrete switching subsystem. The separate GMII/RGMII/RvMII interface offers a path to an application processor or additional switching element. Designers must still allocate pins, bypass capacitance, clocking, reset, and management connections according to the complete manufacturer package data before schematic capture is approved.
Recommandé
Embedded Control-System Gateway
BCM5396IFB can serve as the Ethernet aggregation element in a gateway connecting multiple industrial controllers or remote I/O nodes to an embedded host. Sixteen SGMII/SerDes interfaces consolidate the links, and the non-blocking fabric prevents an architectural headroom bottleneck at the advertised 17-Gigabit aggregate capacity. Jumbo-frame support up to 9 KB can benefit large diagnostic or control payloads when the entire path supports those frames. Before selecting it for a safety- or production-critical system, engineers still need verified temperature, longevity, radiation, and update-policy information that is not present in the supplied excerpts.
Recommandé
Telecom Ethernet Edge Equipment
BCM5396IFB is suitable for telecom-oriented Ethernet edge equipment requiring numerous integrated Gigabit ports and a separate uplink. IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x behavior, including PAUSE-frame flow control, provides a standards-oriented foundation for managed traffic. The seventeen MACs and 256-KB buffer support centralized frame handling, while the 17-Gigabit non-blocking fabric targets sustained multiport throughput. Qualification for carrier deployment additionally requires checking electrical, temperature, reliability, regulatory, and lifecycle requirements from documents not included in the verified excerpts.
Recommandé
Video Network Aggregation
BCM5396IFB can aggregate up to sixteen Gigabit Ethernet video endpoints into an uplink in a professional media or surveillance installation. Its non-blocking 17-Gigabit fabric and 256-KB packet buffer provide a consolidated switching resource, while frames up to 9 KB can accommodate larger video packets when cameras and the rest of the network are configured consistently. The SGMII/SerDes ports can support suitable copper or optical physical layers. Design validation must include total offered load, multicast behavior, congestion control, thermal performance, and uninterrupted high-speed trace routing on the BGA PCB.

Notes de conception
Treat all sixteen SGMII/SerDes links as controlled-impedance differential pairs. Use the manufacturer’s BGA ball map and reference design to set length tolerance, pair separation, via geometry, and layer transitions; route over continuous ground planes and avoid stubs. A single discontinuity can create reflections that impair signaling margin even when the nominal 17-Gigabit switching fabric is correct.
Allocate separate low-impedance power and ground planes or vias according to the complete datasheet, and place high-frequency decoupling close to the relevant BGA balls. Do not infer voltage values or capacitor values from the available excerpts. Confirm startup sequencing, clock sources, reset behavior, and power-budget limits against the manufacturer documentation before schematic and layout release.
Do not substitute a switch merely because it also supports Gigabit Ethernet. BCM5396IFB’s replaceability depends on exact BGA geometry, ball functions, voltage domains, SerDes characteristics, MAC resources, management interface, and thermal limits. The supplied cross-reference search found no verified drop-in equivalent, so any proposed part must be treated as a redesign until its documentation proves compatibility.
Informations de conformité
The verified excerpts identify IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x compliance, but they do not provide RoHS, REACH, halogen-free, lead-free, conflict-minerals, or automotive qualification declarations.
