BCM5387IFBG - 8-Port SGMII Ethernet Switch | Broadcom
MPN: BCM5387IFBG ✗ Cuối đờiBCM5387IFBG Tóm tắt
An Ethernet switch controller is an interface IC that manages frames between network ports and an upstream system. In this product hierarchy, the BCM5387 belongs to Ethernet switches, interface ICs, and integrated circuits. Its eight-port SGMII architecture allows multiple Gigabit Ethernet connections to be consolidated behind a high-speed serial interface, reducing the number of physical network interfaces required in a multi-port networking system.
The principal verified feature of the BCM5387IFBG is its 8-port SGMII switching capability. The device integrates the packet buffer, eight media access controllers, address management, and the non-blocking switch controller into one monolithic IC. This integration reduces the external component count required to implement a multi-port switching subsystem while retaining centralized frame handling and MAC control functions.
The BCM5387 is manufactured using 0.13 µm CMOS technology. That process information comes from the preliminary manufacturer data sheet and identifies the device as a highly integrated high-speed switch solution. The supported Ethernet specifications include conventional Ethernet, Fast Ethernet, 1000BASE-T-related operation described by IEEE 802.3ab, and IEEE 802.3x MAC-control operation. Detailed electrical limits, clock requirements, register defaults, and transceiver characteristics are not included in the supplied web data.
Typical uses include eight-port Gigabit Ethernet aggregation, industrial network gateways, managed network equipment, set-top and customer-premises networking, and centralized port switching. The SGMII interface is particularly useful when the system needs a compact digital interface between the switch controller and external physical-layer transceivers rather than integrating copper and fiber PHYs inside the switching IC.
Designers should treat the available document as preliminary and verify the production device's complete pin list, power rails, clocking, reset requirements, and electrical characteristics before layout release. Because the supplied sources do not identify the exact BCM5387IFBG package or provide a complete pinout, the package and pin data remain unresolved rather than being inferred from the orderable part number.
This page consolidates the verified distributor and manufacturer-document information available as of October 28, 2026, and separates confirmed facts from unresolved engineering data. It also records pricing observations, application context, design cautions, and the absence of independently verified drop-in replacements, helping engineers assess sourcing and validation work before committing the legacy switch controller to a new design.

Ứng dụng tiêu biểu
BCM5387IFBG phù hợp cho 6 Áp dụngs: Eight-Port Gigabit Ethernet Gateway, Managed Network Edge Equipment, Industrial Network Aggregation, Set-Top and Customer-Premises Networking, Managed Switch Line Card, Industrial Control and Automation Gateway.
Eight-Port Gigabit Ethernet Gateway
The BCM5387IFBG fits an eight-port gateway because it combines eight SGMII-facing MACs with a non-blocking switch controller in one monolithic 0.13 µm CMOS device. The switch can receive traffic from eight Gigabit Ethernet physical layers and present a consolidated network connection to an upstream processor or communications controller. According to the Broadcom preliminary data sheet, the integrated packet buffer and address management support centralized frame handling. Using SGMII keeps the digital port interface compact while external PHYs provide the physical copper or fiber connections. Before layout, engineers must obtain the production package drawing, verify voltage and timing requirements, and confirm that the device temperature grade, clocking scheme, and supply plan meet the gateway specifications.

Managed Network Edge Equipment
The BCM5387IFBG is appropriate for managed network-edge equipment that needs eight SGMII ports and centralized frame processing. Its eight integrated media access controllers, address-management function, packet buffer, and non-blocking switch controller provide the core switching functions described in the Broadcom preliminary data sheet. A system processor can use the supported IEEE 802.3x MAC-control capability to manage flow control and network access. The architecture is useful where dedicated PHY components are preferred over a switch with integrated copper or fiber PHYs. Engineering validation must still cover register behavior, clock generation, initialization sequencing, and the production device's electrical limits, because those details are not fully present in the preliminary source document.
Được đề xuất
Industrial Network Aggregation
The BCM5387IFBG can support industrial network aggregation when the product requires eight high-speed serial Ethernet ports and external industrial PHYs. Its 0.13 µm CMOS switch implementation combines packet buffering, eight MACs, address management, and a non-blocking switch controller, matching the Broadcom preliminary data sheet description. The SGMII boundary permits the physical layer to be selected independently for copper, fiber, or isolated communications paths. The part is not presented as temperature-qualified or lifecycle-confirmed because the supplied data does not establish either point. A production industrial design should therefore request the released ordering information, confirm the selected grade's temperature range, and validate power sequencing and electromagnetic behavior alongside the enclosure and cable system.

Set-Top and Customer-Premises Networking
The BCM5387IFBG is applicable to set-top and customer-premises networking designs that aggregate several Gigabit Ethernet connections through SGMII. Eight integrated MACs and a non-blocking switch controller allow a system to connect multiple service endpoints while preserving centralized address management. This arrangement is especially useful when external PHY devices provide copper or fiber reach. The Broadcom preliminary data sheet confirms IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x compliance, providing a defined basis for Ethernet behavior. Before adopting this mature architecture, teams should verify long-term procurement, current software support, production test access, and the complete package and pin definitions directly with Broadcom or an authorized representative.

Managed Switch Line Card
The BCM5387IFBG can serve as the switching element of a managed line card when eight SGMII ports are required. The integrated packet buffer, media access controllers, address management, and non-blocking controller are the verified architectural elements, allowing the line card to connect eight external PHYs while a host processor performs configuration and policy management. IEEE 802.3x support provides the specified basis for MAC-control behavior. Designers should calculate interface timing margins and power budgets from the released production data rather than the preliminary document. They should also verify PCB escape routing, thermal performance, magnetics or optical-module requirements, and whether an eight-port SGMII topology offers sufficient value relative to a newer switching device with broader lifecycle support.
Được đề xuất
Industrial Control and Automation Gateway
The BCM5387IFBG can support a multi-segment industrial control gateway by switching eight SGMII Ethernet connections while external PHYs handle physical-layer implementation. The confirmed integration of eight MACs, a packet buffer, address management, and a non-blocking switch controller makes it useful where multiple machine or plant networks must be consolidated. IEEE 802.3x support enables standards-based MAC control, while the SGMII interface can simplify connections to isolated PHY links. The supplied evidence does not confirm industrial temperature qualification, functional-safety status, or current lifecycle commitments. Consequently, the device should enter a new control platform only after Broadcom documentation verifies those requirements and the manufacturer or authorized representative confirms availability and change-control status.

Ghi chú thiết kế
Do not treat the available preliminary data sheet as a complete production specification. Before committing a PCB or firmware, obtain the current BCM5387 data sheet, package drawing, pin table, errata, ordering guide, and software documentation. In particular, verify supply rails, absolute maximum ratings, timing, reset behavior, clock sources, and thermal limits. The supplied web excerpts confirm the 8-port SGMII architecture and IEEE support but do not provide enough electrical data to release a layout safely.
Plan the SGMII interface as a high-speed digital interface after the released device specification is available. Keep PHY-to-switch traces short, provide continuous reference planes, control impedance according to the production requirements, and avoid unnecessary stubs or test-point discontinuities. Match the external PHY, connector, magnetics, and clock architecture to the manufacturer reference design. No trace-length or impedance value should be invented from the preliminary document because those implementation limits are not present in the verified data.
Create the power budget from released operating-current and voltage limits, then verify startup sequencing across the switch controller and every external SGMII PHY. Place local bulk and high-frequency bypass capacitance at the device supply pins according to the final datasheet and reference layout. Because the verified sources do not disclose BCM5387IFBG supply voltage, current, or junction-temperature limits, the actual dissipation and decoupling values must remain unspecified until current manufacturer data is obtained.
Thông tin tuân thủ
