MPN: BCM5395MKFBG ✓ نشطBCM5395MKFBG نظرة عامة
An Ethernet switch is a network-interface semiconductor that connects multiple Ethernet ports and forwards frames according to MAC addresses. A Gigabit Ethernet switch with integrated PHYs combines the physical-layer transceiver functions with switching and packet-buffer logic. This integration reduces the number of separate network components required in a compact design and provides a common interface for 10 Mbps, 100 Mbps, and 1 Gbps Ethernet connections.
The BCM5395 family provides five integrated Gigabit PHYs and packet-buffer capacity within one Broadcom device. The listing identifies the part as a five-port switch and describes support for MII, RGMII, GMII, and RvMII operating interfaces. These interface choices support connection to a host processor, embedded controller, or another Ethernet block when the selected board configuration and electrical design meet the device requirements.
The BCM5395 implementation uses CMOS technology and is categorized as an Ethernet interface and switching IC. Its five integrated PHYs are intended to reduce system complexity compared with a design using discrete Ethernet transceivers. The device is also associated with IEEE 802.3az Energy Efficient Ethernet support, making it relevant to network equipment that emphasizes power efficiency while retaining multiple Gigabit Ethernet ports.
Typical applications include industrial Ethernet gateways, home-automation controllers, set-top and media devices, access-point equipment, embedded network appliances, and industrial control systems. For these applications, the five integrated PHYs can support multi-port copper networking while preserving a compact board layout. The available device information does not define the exact pin assignments, package dimensions, or detailed electrical limits.
When designing around BCM5395MKFBG, verify the exact package land pattern, power rails, clock requirements, PHY characteristics, and interface voltage levels against the Broadcom datasheet before layout. Keep high-speed traces short, provide the recommended power and decoupling network, and follow the reference design for magnetics or PHY copper connectivity. This device should be selected only after checking that all five ports, supported media interfaces, and environmental requirements match the target system.
This product page organizes the confirmed BCM5395MKFBG specifications, sourcing references, application context, and engineering trade-offs. It also separates explicitly documented facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers evaluate the switch without relying on incomplete distributor summaries.

التطبيقات النموذجية
BCM5395MKFBG مناسب لـ 6 التطبيقs: Industrial Ethernet Gateway, Home Automation Controller, Network Access Equipment, Industrial Control Terminal, Networked Measurement Equipment, Networked Audio and Video Equipment.
Industrial Ethernet Gateway
The BCM5395MKFBG fits an industrial Ethernet gateway that needs five local copper ports while using one network interface device. Its five integrated PHYs support 10 Mbps, 100 Mbps, and 1 Gbps links, while the MII, RGMII, GMII, and RvMII options provide paths to a host controller. The -40 C to +105 C ambient range supports industrial environments, although isolation, surge protection, grounding, and product safety requirements must be addressed separately.
موصى به
Home Automation Controller
A home-automation controller can use the BCM5395MKFBG to consolidate several wired Ethernet connections into one switching component. The five integrated PHYs avoid requiring five separate Ethernet transceiver blocks, and compatibility with 10 Mbps and 100 Mbps devices allows mixed-speed networks. The controller still needs an appropriate host interface, clocking, Ethernet magnetics strategy, and careful separation between external copper networks and low-voltage circuitry.
موصى به
Network Access Equipment
The BCM5395MKFBG is appropriate for access equipment that needs several Gigabit Ethernet service ports in a compact assembly. Its integrated five-port switching architecture can feed local ports and simplify the physical implementation of copper Ethernet connectivity. MII, RGMII, GMII, and RvMII support gives the board designer options for processor attachment, while IEEE 802.3az Energy Efficient Ethernet can assist with system power-management objectives.
موصى به
Industrial Control Terminal
In an industrial control terminal, the BCM5395MKFBG can provide five Ethernet connections for service equipment, local controllers, sensors, and supervisory systems. Supporting legacy 10 Mbps and 100 Mbps devices is useful when the equipment fleet includes older nodes, while 1 Gbps links accommodate modern data transfer. The design must maintain suitable separation and grounding between external Ethernet cabling and sensitive control circuitry.
موصى به
Networked Measurement Equipment
Networked measurement equipment can use the BCM5395MKFBG to provide multiple service and management Ethernet ports on an instrument. The five integrated PHYs permit a mix of 1 Gbps links and 10 Mbps or 100 Mbps legacy equipment while maintaining a centralized switching function. Timing-sensitive instrument designs should verify clock sources, interface timing, isolation strategy, and grounding against the manufacturer reference design before production.
موصى به
Networked Audio and Video Equipment
The BCM5395MKFBG can serve networked audio or video appliances that need several Ethernet service connections and backward compatibility with slower equipment. One integrated switch can connect controllers, displays, storage nodes, and service interfaces while supporting 1 Gbps links for high-volume traffic. For AV equipment, the implementation must account for ground isolation, cable shielding, fanout behavior, and any latency constraints imposed by synchronized media paths.

ملاحظات التصميم
Use the Broadcom BCM5395 reference layout and the exact package drawing before assigning PCB layers or ball locations. Route MII, RGMII, GMII, and RvMII signals as controlled-length interfaces where the selected mode requires it, and keep clocks away from noisy switching and Ethernet magnetics areas. Confirm the supported media mode for the board because each interface can impose different topology, voltage, and timing constraints.
Implement every supply rail specified by the Broadcom datasheet and place bypass capacitance at the package power connections with short return paths. Confirm whether the integrated PHYs require external Ethernet magnetics and how the selected reference network handles isolation. Do not estimate supply current from the 1 Gbps signaling rate; use the worst-case port, media, and temperature conditions defined for the complete device configuration.
Keep the five Ethernet channels physically organized, with copper routing and magnetics or termination structures arranged according to the reference design. Maintain consistent return paths, controlled differential-impedance routing, and appropriate separation between each port. Route management and high-speed parallel interfaces away from external cable entry points where possible, and review connector, enclosure, and grounding decisions with the final EMC requirements in mind.
Do not treat any Ethernet switch with five ports as a drop-in replacement for BCM5395MKFBG. A valid substitution must match the BGA land pattern, ball functions, media interfaces, electrical levels, clocking, power rails, thermal limits, and management firmware expectations. Confirm the exact ordering code and package dimensions, and review any silicon revision or errata before releasing production artwork.
