KSZ9563RNXI - 3-Port Gigabit Ethernet Switch | Microchip
Teilenummer: KSZ9563RNXI ✓ AktivKSZ9563RNXI Übersicht
A Gigabit Ethernet switch is a network-semiconductor device that links Ethernet ports and manages frame forwarding between connected systems. Within the broader hierarchy, the KSZ9563RNXI is an Ethernet switch controller, an interface IC, a network semiconductor, and a system-on-chip integration of Ethernet MAC, physical-layer, timing, and management functions. Configurable RGMII, MII, and RMII interfaces allow it to connect with processors, field-programmable gate arrays, and other Ethernet-capable controllers using different parallel bus arrangements.
The device provides IEEE 1588v2 Precision Timing Protocol and EtherSynch support, adding deterministic timing capabilities for synchronization-oriented networks. Its feature set also includes Audio Video Bridging, Energy Efficient Ethernet, Wake-on-LAN, Quality of Service, and LinkMD cable diagnostics. Together, these functions address synchronization, traffic prioritization, power management, remote activation, and physical-link troubleshooting in connected industrial equipment.
The KSZ9563RNXI operates from a 1.8 V, 2.5 V, or 3.3 V supply, supporting systems with common mixed-voltage I/O rails. Its 64-QFN package provides a compact surface-mount footprint for industrial control, automation, communications, and embedded-network designs. The manufacturer lists the device for industrial-temperature operation, while its exact minimum and maximum junction and ambient ratings should be confirmed in the KSZ9563R data sheet before final environmental qualification.
Typical applications include industrial Ethernet switches, factory-floor gateways, motion-control equipment, networked sensors, embedded control systems, and synchronized communications infrastructure. RGMII is appropriate for a processor or FPGA requiring a high-speed parallel Ethernet connection, while RMII reduces pin demand in lower-bandwidth designs. MII provides compatibility with established parallel Ethernet interfaces that may already exist in legacy control equipment.
Design the power rails so that all three listed supply voltages meet the voltage, sequencing, and decoupling requirements stated in the manufacturer data sheet. Place the input, regulator, and interface bypass capacitors close to their associated device pins, and route high-speed RGMII signals as a short, controlled-impedance group. Differential Ethernet traces also require careful reference-plane continuity and through-transition matching.
This page organizes the switch features, interface choices, sourcing information, and engineering considerations for engineers evaluating the KSZ9563RNXI. It also identifies where application-specific timing, thermal, pin-assignment, and environmental qualification must be completed before the device is released into volume production.

Wichtigste Unterscheidungsmerkmale

- Integrated synchronization and network-management functions (vs. KSZ9563)
Designhinweise
Use the manufacturer reference schematic and recommended decoupling values for the 1.8 V, 2.5 V, and 3.3 V rails. Place each bypass capacitor adjacent to its intended supply pin, keep the high-current return path continuous under the device, and separate noisy switching nodes from sensitive clock and interface traces. Confirm startup and shutdown sequencing against the operating requirements in the KSZ9563R data sheet.
Treat RGMII as a matched, high-speed parallel interface rather than an ordinary set of digital signals. Route clock and data as a compact group over a continuous reference plane, observe the manufacturer’s length and timing guidance, and avoid stubs or unnecessary layer transitions. MII and RMII still require controlled impedance, but their timing constraints and edge rates differ from RGMII.
Use the exact 64-QFN land pattern and exposed-pad assembly details from the manufacturer documentation. Do not substitute a generic 64-pin QFN footprint because pad dimensions, thermal-via requirements, and exposed-pad geometry can differ. Apply the recommended solder-mask and paste pattern and verify the exposed pad’s electrical connection in the package drawing before releasing the PCB files.
Do not interpret the shorter KSZ9563 family name as proof that every ordering code is a drop-in substitute. Confirm the exact suffix, temperature grade, package dimensions, exposed-pad implementation, interface pins, and supply assignments. Also avoid treating the KSZ9563RNXI-TR ordering suffix as an electrical alternative because it identifies a packaging configuration for the same device.
Compliance-Informationen
The KSZ9563RNXI is listed as RoHS compliant. The manufacturer identifies the device for industrial-temperature operation. No separate AEC-Q100 qualification claim is shown for this ordering code.
