BCM53108IMLG - 9-Port FE Switch with EEE | Broadcom
部品番号: BCM53108IMLG ✗ 生産終了BCM53108IMLG 概要
An Ethernet switch is a network-semiconductor device that connects multiple physical-layer ports to a higher-layer network processor or switching fabric. The BCM53108IMLG combines multiple Fast Ethernet endpoints with EEE capability, allowing compatible links to reduce power consumption when traffic is idle. This makes the device relevant to gateways, routers, industrial Ethernet equipment, access systems, and embedded network appliances requiring several 100BASE-T connections.
The part is identified in the available listing as a Broadcom interface IC and is categorized as an Ethernet interface device rather than a general-purpose logic IC. Its 9-port FE architecture provides a concentrated set of Fast Ethernet connections in one device, reducing the number of discrete network-interface components required in a multi-port product. EEE support can also help reduce system power when connected devices and link partners implement the same energy-saving behavior.
The package and exact pinout are not available in the supplied product records. Consequently, a footprint replacement should not be selected from the part description alone. Before schematic capture, PCB layout, or production sourcing, engineers should obtain the manufacturer datasheet and compare power pins, port interfaces, management signals, reference clock requirements, reset behavior, and package drawing against the target design.
Typical uses include industrial routers, building-control gateways, IP-camera and surveillance systems, embedded Linux appliances, and Ethernet aggregation products. In each case, the 9-port Fast Ethernet arrangement can simplify board partitioning, while EEE can lower activity-related power when both ends of a link support the feature.
This page combines the confirmed product identity, switch-port count, EEE feature, packaging information, and practical sourcing context with design guidance that helps distinguish a confirmed drop-in replacement from a merely similar Ethernet interface. A final replacement decision must use the manufacturer’s package drawing and pin-description tables rather than distributor category labels alone.

主な用途
BCM53108IMLG の用途: 6 件s: Industrial Ethernet Gateway, Building-Control Network Gateway, IP Camera and Surveillance Hub, Embedded Linux Network Appliance, Carrier Ethernet Edge Device, Smart-Home Controller Hub.
Industrial Ethernet Gateway
The BCM53108IMLG fits industrial gateways that need nine Fast Ethernet connections for sensors, controllers, service equipment, or plant networks. Its confirmed 9-port FE switching architecture can consolidate multiple links into one interface device and simplify board partitioning. EEE support may reduce activity-related power when connected equipment supports compatible idle behavior. Before schematic release, verify the manufacturer’s voltage limits, clock requirements, port mapping, management interface, and thermal ratings against the industrial enclosure and power budget.
おすすめ
Building-Control Network Gateway
The BCM53108IMLG is suitable for building-control gateways that aggregate floor, room, lighting, HVAC, and access-control Ethernet endpoints. Nine Fast Ethernet ports reduce the number of separate interface devices required in a controller, while EEE can support lower link activity when the network is quiet. The design must still account for Ethernet magnetics, connector layout, surge and isolation requirements, and the enclosure temperature. Verify management, reset, and clock details in the manufacturer datasheet before selecting the part for a safety-adjacent building system.
おすすめ
IP Camera and Surveillance Hub
The BCM53108IMLG can support network hubs or recording appliances that bring together multiple Fast Ethernet camera connections. Its nine-port arrangement is appropriate for compact installations that need several camera links without distributing the interfaces across multiple switching devices. EEE may lower activity-related consumption when cameras and the connected switch support idle-power operation. Because video traffic can be bursty, engineering validation should cover buffering, latency, thermal rise, and link-partner behavior. Confirm the exact port features and timing requirements from Broadcom documentation.
おすすめ
Embedded Linux Network Appliance
The BCM53108IMLG is relevant to embedded Linux routers, access points, and network appliances requiring several Fast Ethernet connections for management, service, and uplink ports. Consolidating those endpoints in a 9-port FE switch can simplify routing through a host processor while preserving dedicated physical interfaces. EEE support can assist power reduction on lightly loaded links. The system design should validate processor bus integration, management signaling, reference clocking, reset behavior, and power sequencing against the manufacturer documentation, particularly for Linux images that enable EEE through interface drivers.
おすすめ
Carrier Ethernet Edge Device
The BCM53108IMLG can be evaluated for edge equipment requiring multiple Fast Ethernet service ports, such as branch gateways, media converters, and small access platforms. Its 9-port FE configuration provides a practical concentration point for copper Ethernet interfaces, and EEE supports lower idle activity where compatible links are present. Carrier-grade designs still need separate consideration of clock quality, jitter, recovery behavior, port isolation, surge withstand, and environmental qualification. Those parameters must be confirmed from the manufacturer datasheet before the device is treated as a production-grade network component.
おすすめ
Smart-Home Controller Hub
The BCM53108IMLG fits smart-home controllers that connect IP cameras, access points, room controllers, and other Ethernet-powered devices. A nine-port Fast Ethernet arrangement can support a concentrated wired network while EEE may reduce power when links are idle. Product-level design must ensure the selected magnetics and connectors match the electrical requirements, and system firmware should coordinate EEE with connected-device behavior. Temperature, power sequencing, reset, and management functions should be checked against the manufacturer datasheet before deployment across mixed consumer and commercial devices.

設計ノート
Do not release the PCB land pattern until the current Broadcom package drawing and pin table have been checked. Confirm pin count, package outline, pad dimensions, exposed-pad or thermal-via requirements, pin-one orientation, solder-mask clearance, and courtyard limits. A distributor category label such as interface IC is not sufficient to establish mechanical compatibility, and the verified BCM53108IMLG records do not provide the package designation.
Plan the supply network around the exact voltage rails, sequencing, and current limits stated in the manufacturer datasheet. Separate switching and sensitive circuitry where practical, use local high-frequency bypass capacitors at the device supply pins, and provide clean return paths from every ground connection. The BCM53108IMLG records confirm the Ethernet function but do not state the operating supply voltage or consumption, so those values must not be inferred from related BCM devices.
Preserve a controlled return path beneath the switch device and keep the Ethernet port interfaces away from sensitive clock or management circuitry. Follow the manufacturer’s reference layout for external crystals or oscillators, reset circuitry, magnetic-interface components, and decoupling. Keep copper and component placement consistent with the recommended land pattern, and review differential pair routing and isolation requirements against the applicable Ethernet interface documentation.
Do not treat BCM53108VIMLG or another related ordering code as a drop-in substitute without a mechanical and pin-level comparison. Validate supply voltage, ground assignments, reference-clock frequency, reset polarity, port mapping, management signals, and package drawing against BCM53108IMLG. Also account for MSL 3 handling: manage sealed storage, moisture exposure, reflow, and rework according to the manufacturer’s handling guidance.
コンプライアンス情報
The product records confirm MSL 3 (168 hours) handling and tray packaging but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields require confirmation from the manufacturer documentation.
