KSZ9563RNXC - 3-Port Gigabit Ethernet Switch | Microchip
Teilenummer: KSZ9563RNXC ✓ AktivKSZ9563RNXC Übersicht
An Ethernet switch is a network-semiconductor category that connects multiple Ethernet ports, forwards frames between them, and manages physical-layer network traffic. The KSZ9563 integrates three Gigabit Ethernet ports into one device, reducing the component count required for a multiport network node compared with discrete Ethernet PHY implementations. This integration places the KSZ9563 within the broader hierarchy of Ethernet controllers, network interface controllers, and semiconductor components.
The switch combines RGMII, RMII, and MII host interfaces with IEEE 1588v2 timing support. Microchip also identifies AVB, Energy Efficient Ethernet, Wake-on-LAN, quality-of-service, and LinkMD features for the KSZ9563 family. These capabilities support designs requiring precise packet timing, traffic prioritization, reduced link energy, remote wake behavior, and PHY-status monitoring within a compact network interface subsystem.
The RGMII interface supports high-throughput connections to a host processor or dedicated switching logic, while RMII and MII provide alternatives for systems using different host bus architectures. IEEE 1588v2 Precision Timing Protocol allows participating network devices to maintain precise time relationships, which is useful when measurements or events must be correlated across multiple nodes. EtherSynch provides additional timing synchronization capability for compatible network designs.
Typical uses include industrial Ethernet equipment, factory automation controllers, automotive in-vehicle networking systems, synchronized test equipment, communications infrastructure, and embedded network gateways. In these systems, the three integrated ports can connect local endpoints and upstream network segments while reducing the number of separate Ethernet PHY devices required at the board edge.
The principal design consideration is interface selection. A board using RGMII must provide the corresponding data and control paths, while RMII and MII designs require different clocking and signal arrangements. Validate the selected interface against the host processor, magnetics, connector layout, reference clock, and reset architecture before finalizing the PCB because changing host-interface choices is not a footprint-only substitution.
This page organizes the KSZ9563RNXC capabilities, application guidance, package information, and procurement questions into one engineering reference. It also distinguishes confirmed device functions from specifications that require confirmation in the manufacturer datasheet, helping designers plan interface selection and PCB implementation before releasing hardware.

Typische Anwendungen
KSZ9563RNXC ist geeignet für 6 Anwendungs: Industrial Ethernet Controller, Automotive In-Vehicle Network Gateway, Synchronized Test and Measurement Equipment, Communications Network Gateway, Factory Automation Endpoint, Embedded Network Appliance.
Industrial Ethernet Controller
The KSZ9563RNXC fits industrial controllers that need three local Gigabit Ethernet connections and deterministic network timing without a separate switch for every port. Its MII, RMII, and RGMII host interfaces allow the controller to match different embedded processors, while IEEE 1588v2 Precision Timing Protocol and EtherSynch support synchronized events across equipment. Quality-of-service support is useful when control traffic must retain priority over less time-sensitive traffic. The 64-QFN, 8 x 8 mm package also supports compact board layouts, although differential routing, magnetics isolation, reference clocks, and power integrity require careful implementation.
Automotive In-Vehicle Network Gateway
The KSZ9563RNXC is suitable for evaluating a multiport in-vehicle Ethernet gateway where compactness and precise timing are important. Three Gigabit Ethernet ports can support links to vehicle domains or external test equipment, while IEEE 1588v2 timing allows distributed events to be referenced to a common time base. AVB support can assist audio and video traffic handling, and LinkMD provides PHY diagnostic functions for cable and link monitoring. Before production use, verify the device's automotive qualification, temperature range, supply limits, and any platform-specific network requirements in the manufacturer documentation.
Synchronized Test and Measurement Equipment
The KSZ9563RNXC fits synchronized test equipment that must collect or distribute data across several Gigabit Ethernet endpoints with accurate time relationships. IEEE 1588v2 Precision Timing Protocol provides a mechanism for coordinated timing across participating devices, while EtherSynch extends the synchronization feature set. The choice among RGMII, RMII, and MII should follow the acquisition controller or host processor interface. Engineers should account for clock jitter, trace skew, PHY magnetics, and deterministic reset behavior when defining the synchronization architecture.
Communications Network Gateway
The KSZ9563RNXC can form the switching core of a compact communications gateway that must consolidate several Gigabit Ethernet links. Three integrated ports reduce component count compared with separate PHY arrangements and allow upstream connectivity alongside local endpoints. Quality-of-service support provides a mechanism for prioritizing selected traffic, while Energy Efficient Ethernet can reduce link activity when traffic demand permits. Wake-on-LAN supports remote activation, making the device relevant to managed gateways and distributed service nodes. System-level validation should include boot sequencing, interface mode configuration, cable diagnostics, and thermal performance.
Factory Automation Endpoint
The KSZ9563RNXC is appropriate for factory automation equipment combining multiple Ethernet-connected sensors, controllers, and service ports. IEEE 1588v2 and EtherSynch support coordinated timing when production events must be correlated across machines, while AVB can assist networks carrying synchronized audiovisual data. The three-port architecture provides a practical way to combine local machine control with plant-level connectivity. Use RGMII when the host interface requires high parallel throughput, or evaluate RMII and MII for simpler embedded host connections. Confirm environmental qualification and long-term supply before deploying the switch in production machinery.
Embedded Network Appliance
The KSZ9563RNXC fits embedded network appliances requiring three Gigabit Ethernet ports in a compact 64-QFN package. Multiple host-interface options help align the switch with an application processor, communications controller, or custom network subsystem. Quality-of-service support is valuable for traffic prioritization, Energy Efficient Ethernet can lower link energy under suitable operating conditions, and LinkMD assists cable diagnostics. WOL can support remotely managed appliances. The implementation should reserve clean power rails, controlled reference clocks, proper magnetic-component isolation, and differential-pair routing that follows the selected Ethernet interface and PCB stack-up requirements.

Designhinweise
Assign the host interface before routing the board because MII, RMII, and RGMII require different signal groups, clock arrangements, and timing constraints. Keep each Ethernet differential pair routed as a controlled-impedance pair with continuous reference planes and minimize vias and stubs. Follow the manufacturer's recommended 50-ohm single-ended and differential-impedance guidance, and place magnetics or isolation components where required by the final Ethernet topology.
Partition the switch's digital, analog, and Ethernet-related supplies according to the manufacturer power-supply recommendations. Place local high-frequency bypass capacitors beside the relevant supply pins and keep return-current paths short. Validate startup, current limits, regulator headroom, and sequencing across worst-case Ethernet activity. Use the electrical-characteristics table to calculate dissipated power from the actual supply voltage and measured device current rather than assuming the idle condition.
Treat the selected host interface as a timing-sensitive synchronous bus. Match trace lengths according to the datasheet requirements, provide a clean reference clock with controlled jitter, and isolate high-current Ethernet paths from sensitive clock and data routes. For IEEE 1588v2 or EtherSynch systems, include clock-distribution and network-delay budgets so synchronization accuracy remains predictable across all three ports.
