KSZ9563RNXI - 3-Port Gigabit Ethernet Switch | Microchip
MPN： KSZ9563RNXI ✓ 啟用中KSZ9563RNXI 概覽
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.

典型應用
KSZ9563RNXI 適用於 6 應用s: Industrial Ethernet Gateways, Factory Automation Controllers, FPGA-Based Network Equipment, Precision-Timing Network Infrastructure, Networked Sensors and IoT Gateways, Audio-Video Network Bridges.
Industrial Ethernet Gateways
The KSZ9563RNXI fits industrial gateways that combine a 10/100/1000 Ethernet MAC with multiple downstream network connections. Its three-port switch architecture can organize links among a controller, communications module, and service interface, while LinkMD assists physical-link diagnosis. The configurable RGMII, MII, and RMII interface allows the gateway to connect different generations of embedded processors without changing the switch function. IEEE 1588v2 and EtherSynch add value where equipment must maintain precise synchronization across an Ethernet network.
推薦
Factory Automation Controllers
The KSZ9563RNXI is suitable for factory automation controllers that need deterministic Ethernet connectivity alongside machine-control functions. Its IEEE 1588v2 Precision Timing Protocol and EtherSynch support are useful when controllers coordinate distributed motion, sampling, or process events over an Ethernet network. Quality of Service can prioritize selected traffic classes, while the 64-QFN, 8 mm by 8 mm package supports compact embedded control boards. The RGMII option provides a high-speed host connection when the controller processor includes a compatible Ethernet MAC.
推薦
FPGA-Based Network Equipment
The KSZ9563RNXI can serve FPGA-based network equipment requiring a flexible Ethernet host interface. RGMII is suitable for a high-throughput FPGA connection, while MII and RMII support designs with different parallel-bus constraints. The three-port switch architecture consolidates a Gigabit Ethernet MAC and multiple network connections without requiring separate switching devices for every link. Audio Video Bridging and QoS may be useful in systems that carry multiple traffic classes, although the design must validate buffering, timing, and interface behavior against the manufacturer data sheet.
推薦
Precision-Timing Network Infrastructure
The KSZ9563RNXI fits timing-oriented network infrastructure because it combines Gigabit Ethernet switching with IEEE 1588v2 Precision Timing Protocol and EtherSynch. These features allow a network node to participate in synchronized communication systems used for industrial measurement, coordinated automation, and embedded timing distribution. The 1.8 V, 2.5 V, and 3.3 V supply options permit integration with common embedded processor rails. Designers should evaluate the data sheet’s clock requirements, timestamp behavior, jitter expectations, and reference circuitry before selecting the device for a specific timing profile.
推薦
Networked Sensors and IoT Gateways
The KSZ9563RNXI supports networked sensors and IoT gateways that need to aggregate several Ethernet links into an embedded system. Its three-port switch architecture provides a compact way to connect a management interface, upstream network, and local endpoint. Wake-on-LAN can support remote activation functions, while Energy Efficient Ethernet addresses link-level energy reduction in connected equipment. RMII may be attractive when the host device has limited pin availability, and LinkMD provides useful diagnostic support when commissioning cable links in installations where physical access is difficult.
推薦
Audio-Video Network Bridges
The KSZ9563RNXI is applicable to audio-video network bridges because it includes Audio Video Bridging alongside Gigabit Ethernet switching and QoS. A bridge design can combine network-facing and endpoint-facing links while prioritizing latency-sensitive traffic where the surrounding network supports the corresponding configuration. The RGMII interface can connect a capable host processor, while MII and RMII accommodate embedded controllers with different interface constraints. The compact 64-QFN package and three-port architecture reduce board area compared with implementing separate switching and traffic-control functions.

主要差異化特點

- Integrated synchronization and network-management functions (對比KSZ9563)
設計說明
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.
合規資訊
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.
