KSZ8463RLI - 3-Port IEEE 1588 Ethernet Switch | Microchip
Teilenummer: KSZ8463RLI ✓ AktivKSZ8463RLI Übersicht
An IEEE 1588v2 Ethernet switch is a network-interface IC that combines Ethernet frame switching with Precision Time Protocol clock synchronization. It sits between an embedded host or processor and physical-layer network interfaces, allowing synchronized time and data traffic to share the same industrial Ethernet infrastructure. The KSZ8463 belongs to the Ethernet switch, network interface controller, industrial Ethernet, and precision synchronization categories.
The KSZ8463RLI provides three 10/100 Ethernet ports, a Management Media Interface for host configuration and control, and support for fiber-based links. Its principal differentiator within the KSZ8463 family is the exact combination of package suffix, temperature grade, and fiber-option configuration designated by RLI. Industrial-grade operation is identified in the verified distributor data, while exact voltage limits, timing values, current consumption, and environmental boundaries require confirmation from the manufacturer datasheet.
The device is intended for industrial automation, synchronized sensor networks, factory-floor equipment, motion-control systems, and communications infrastructure where local Ethernet traffic must be switched alongside precise timing information. Its managed-switch architecture reduces the need for separate bridging hardware while providing a standardized path for synchronized communications across multiple 10/100 network segments.
Fiber support can be useful when equipment must communicate across electrically noisy factory environments or over longer links while retaining synchronization capability. The MII interface allows the switch to connect to an external host controller through a standardized parallel media interface, while PHY-related implementation details and supported copper or fiber configurations should be confirmed against the exact KSZ8463 ordering information.
For a new PCB design, engineers should confirm the 64-pin LQFP footprint, reference clock requirements, MII wiring, strap settings, fiber interface configuration, and power-supply sequencing from the manufacturer datasheet before layout release. Existing KSZ8463RLI boards may use the same family options for alternate temperature or fiber configurations, but those substitutions require package and feature verification rather than name similarity alone.
This product page consolidates current distributor availability, manufacturer family information, package data, and strict same-package alternatives into one engineering reference. It also highlights which electrical and pin-level details remain unavailable in the supplied verified records, helping reduce the risk of an incomplete or electrically incompatible redesign.

Typische Anwendungen
KSZ8463RLI ist geeignet für 6 Anwendungs: Industrial Automation Ethernet, Precision Time Synchronization, Factory Sensor Networks, Motion Control Equipment, Fiber-Backbone Network Equipment, Embedded Network Gateways.
Industrial Automation Ethernet
The KSZ8463RLI fits industrial automation equipment that must exchange ordinary Ethernet traffic while maintaining IEEE 1588v2 synchronization across three 10/100 ports. Place the managed switch between a controller and its field-network interfaces, then use the MII connection for host management and configuration. The three-port architecture reduces the need for separate switching components in compact PLC, I/O, and industrial-control systems. Before layout, verify the supported copper and fiber media configuration, required reference clock, MII pin mapping, and power requirements from the manufacturer datasheet.
Empfohlen
Precision Time Synchronization
The KSZ8463RLI is suitable for equipment that requires IEEE 1588v2 timing across several 10/100 network links. Its managed three-port switch architecture carries communication traffic while supporting synchronized network operation, reducing the number of separate switching and timing functions required in a controller. The MII host interface provides the integration point for a processor or dedicated network controller. System timing accuracy still depends on the selected physical layer, reference clock, cable or fiber medium, firmware configuration, and overall network topology.
Empfohlen
Factory Sensor Networks
The KSZ8463RLI can connect sensor and actuator nodes in a factory network that needs both data exchange and synchronized timing. Its three 10/100 ports support compact local network topologies, while IEEE 1588v2 support helps maintain a common time reference among measurement and control equipment. Use the MII interface to connect the switching function to an embedded controller and confirm whether the required physical links use copper, fiber, or a mixed configuration. The 64-pin LQFP package also requires careful high-speed and power-ground layout.
Empfohlen
Motion Control Equipment
The KSZ8463RLI fits motion-control equipment where synchronized communications can improve coordination between controllers, drives, and sensors. IEEE 1588v2 synchronization is valuable when independently located nodes must execute time-related tasks consistently, while the three-port 10/100 switch consolidates local traffic onto a shared network fabric. The MII interface supports connection to a host controller capable of handling Ethernet management. Validate jitter, timestamp, and clocking behavior against the complete system design because the supplied records do not quantify synchronization accuracy.
Empfohlen
Fiber-Backbone Network Equipment
The KSZ8463RLI is appropriate for industrial network equipment that includes supported fiber links and requires synchronized Ethernet communications. Fiber support can provide isolation from electrical noise and extend connectivity between control cabinets, machinery, and remote industrial nodes. The three 10/100 ports allow local traffic to be combined with a fiber-backed network while retaining IEEE 1588v2 synchronization. The exact KSZ8463 suffix determines the available configuration, so engineers must confirm optical-media requirements, transceiver implementation, and port mapping before committing to the PCB design.
Empfohlen
Embedded Network Gateways
The KSZ8463RLI can serve inside an embedded industrial gateway that connects a host processor to multiple 10/100 network segments. The MII interface supports host-managed switching, while IEEE 1588v2 capability preserves timing information across supported links. This combination is useful for gateways that translate local equipment traffic into an upstream industrial network. Implementation should account for media-interface configuration, clock distribution, firmware support, and the 64-pin LQFP land pattern. The supplied evidence does not identify a fixed internal block diagram, so the manufacturer datasheet remains the controlling design reference.

Designhinweise
Treat the MII and physical-network interfaces as high-speed digital signals. Place decoupling capacitors adjacent to the supply pins, provide a continuous return path beneath signal pairs where applicable, and avoid routing Ethernet or MII traces through noisy power-converter regions. The verified package is 64-pin LQFP, but the supplied records do not provide the pin map, so the manufacturer land pattern must control pad placement.
Confirm the KSZ8463RLI supply limits, recommended operating region, and current consumption from the manufacturer datasheet before selecting regulators or bulk capacitance. Sequence the device only as directed by the manufacturer and account for the combined load of the host MII interface and attached Ethernet PHYs. Using a regulator rated only for the KSZ8463 core would not be safe because the complete board power budget is not present in the supplied data.
Do not substitute another KSZ8463 suffix solely because it uses a 64-pin LQFP. Ordering suffixes may encode temperature grade, fiber capability, or other configuration details, and the supplied search snippets do not quantify those differences. Verify the ordering table, clock requirements, strap settings, fiber-media support, and every MII signal before approving a replacement. This is especially important when changing between RLI, MLI, FMLI, and FRLI configurations.
IEEE 1588v2 performance depends on the complete clocking and network implementation, not only the switch IC. Minimize clock jitter, use the recommended reference-clock topology, maintain consistent media interfaces, and verify synchronization behavior at system level. Copper and fiber links should be brought up according to the manufacturer procedure, with firmware, switch configuration, and endpoint timing validated together under realistic traffic and temperature conditions.
Compliance-Informationen
A search result references Microchip RoHS, REACH, and California Proposition 65 information pages, but it does not provide the underlying declarations or status values. Compliance fields are therefore left unknown rather than inferred.
