KSZ8563RNXI - 3-Port 10/100 Ethernet Switch | Microchip
MPN： KSZ8563RNXI ✓ 啟用中KSZ8563RNXI 概覽
An Ethernet switch is a Layer 2 network-semiconductor device that connects multiple Ethernet ports and transfers frames according to MAC addresses. The KSZ8563RNXI combines two copper Ethernet PHYs, associated MAC units, and one configurable processor-facing MAC port within a single package. This integration reduces board area and simplifies the host interface while retaining dedicated support for IEEE 802.3 Ethernet operation.
The switch supports fault recovery, IEEE 1588 version 2 precise time protocol, AVB, Energy Efficient Ethernet, Wake-on-LAN, QoS, and LinkMD+. These functions make it suitable for managed industrial Ethernet designs that require deterministic traffic handling, link diagnostics, power-management support, or precise timing. A configurable host interface allows the same device family to be adapted to processor architectures using RGMII, MII, or RMII.
Configuration strap pins determine the device operating mode at power-up or software reset. External pull-up and pull-down resistors establish the required strap states, allowing the interface and startup behavior to be selected without a separate programming sequence. The design should account for these straps during schematic capture and PCB layout so that reset behavior matches the intended system configuration.
Typical uses include industrial Ethernet controllers, programmable logic or microcontroller-based network gateways, factory automation equipment, serial-to-Ethernet bridges, and embedded systems that need a compact managed switching function. The two copper ports can support network uplinks or device connections while the configurable MAC port communicates with a host processor.
When evaluating a PCB revision, preserve the manufacturer's recommended decoupling, high-speed interface layout, Ethernet magnetics isolation, and strap-resistor placement. Follow the pin-description table and layout guidance in the KSZ8563R datasheet when assigning tracks. The device combines several high-speed and clock-sensitive functions, so stable supply delivery and controlled differential routing are central to reliable Ethernet performance.
This product page consolidates the device's verified network capabilities, interface options, package information, and replacement considerations. It also provides practical application and design guidance intended to help engineers determine whether the KSZ8563RNXI fits the required Layer 2 feature set and host-interface architecture.

典型應用
KSZ8563RNXI 適用於 6 應用s: Industrial Ethernet Gateway, Embedded Network Controller, Factory Automation Equipment, Serial-to-Ethernet Bridge, IoT Edge Gateway, Network Media Player.
Industrial Ethernet Gateway
The KSZ8563RNXI fits an industrial Ethernet gateway because it combines two integrated 10BASE-T/100BASE-TX ports with a configurable RGMII, MII, or RMII interface to a host processor. The host can then communicate with controllers, sensors, and plant equipment through a compact Layer 2+ switching design. IEEE 1588 version 2 and QoS support are useful where synchronized data and traffic prioritization matter, while LinkMD+ and fault recovery improve link diagnostics. The 64-VQFN package supports compact industrial controller layouts, although magnetic-device isolation, strap resistors, and industrial temperature limits must be handled according to the manufacturer datasheet.
推薦
Embedded Network Controller
The KSZ8563RNXI is well suited to an embedded controller that needs both device-facing Ethernet ports and a processor-facing host interface. Two integrated 10/100 PHYs provide copper connections to external network equipment, while RGMII, MII, or RMII can be selected to match the controller's Ethernet MAC timing. Configuration straps simplify deterministic startup by allowing interface modes to be established with external resistors. Wake-on-LAN can reduce system activity when remote activation is required, and the compact 64-VQFN package helps preserve PCB area compared with separate switch and interface circuitry.
推薦
Factory Automation Equipment
The KSZ8563RNXI can support factory automation equipment that combines a controller with multiple Ethernet-connected instruments. Its two 10/100 copper PHY ports can connect local devices, and the configurable host port can carry frames to a higher-level controller. QoS is useful when operational traffic must be prioritized over less critical traffic, while fault recovery supports operation after link disruptions. IEEE 1588 version 2 and AVB add value for synchronized or time-aware industrial networks. Board designers should use the manufacturer layout guidance to preserve signal integrity around the high-speed host interface and copper PHY connections.
推薦
Serial-to-Ethernet Bridge
The KSZ8563RNXI can form the Ethernet switching element in a serial-to-Ethernet bridge or protocol gateway. A microcontroller or communication processor can use the configurable RGMII, MII, or RMII port while external devices connect through the two 10/100 copper ports. LinkMD+ assists with cable and link status diagnostics, and fault recovery helps maintain service after network disturbances. Wake-on-LAN supports remote activation of unattended equipment. The design must account for Ethernet magnetics, line-side isolation, strap configuration, and the timing limits associated with the selected host interface.
推薦
IoT Edge Gateway
The KSZ8563RNXI is applicable to an IoT edge gateway requiring wired Ethernet connectivity and centralized Layer 2 management. Two integrated 10BASE-T/100BASE-TX PHYs support local device connections, while the configurable host interface links the gateway to an application processor. Energy Efficient Ethernet is valuable for reducing link activity when traffic is intermittent, and Wake-on-LAN can support remotely triggered access. For designs carrying time-sensitive or prioritized traffic, QoS, IEEE 1588 version 2, and AVB provide additional control. Deployment requirements still need to be checked against the documented operating-temperature and qualification limits.
推薦
Network Media Player
The KSZ8563RNXI can support a compact network media player by combining two Ethernet PHY ports with a configurable host MAC interface. One copper connection can serve an access network while the other reaches local media equipment or a secondary network segment. LinkMD+ assists in detecting cable or link problems, while fault recovery helps maintain service following link interruptions. Wake-on-LAN is useful for remotely waking a player, and EEE can reduce power consumption during low-traffic periods. The PCB implementation should separate copper PHY routing from the host interface and follow the manufacturer's guidance for magnetics, grounding, and strap placement.

主要差異化特點
- Integrated two-copper-PHY architecture with a configurable host MAC port (對比KSZ9563RNXI-TR)

- Exact ordering variant with the same base device identity (對比KSZ8563RNXI-TR)
設計說明
Place the configuration strap pull-up and pull-down resistors close to their associated KSZ8563RNXI pins and follow the recommended values in the manufacturer datasheet. Straps are sampled at power-up or software reset, so unstable levels or unintended reset behavior can place the switch in the wrong interface mode. Review the final schematic against the strap table before releasing the PCB, and preserve access to the configuration and reset behavior during board bring-up.
Route RGMII, MII, and RMII signals as a complete high-speed interface group, using the manufacturer's recommended topology and impedance-controlled routing rules. Keep clock, data, and associated source-synchronous signals in a tightly controlled environment, with vias and stubs minimized where the layout guidance calls for them. Verify that the selected host interface matches the controller timing and that the copper PHY sections maintain the separation required by the network design.
Implement the supply-network and decoupling arrangement specified in the KSZ8563R datasheet, including the exposed-pad connection and any recommended bulk capacitance. Keep switching or high-current return paths away from sensitive Ethernet and host-interface areas. The exact supply voltage, capacitor values, and exposed-pad requirements must be taken from the manufacturer document rather than inferred from the package description, because reliable startup and low-noise operation depend on those implementation details.
Do not treat a matching VQFN outline as proof of drop-in compatibility. Compare every ball assignment, exposed-pad connection, configuration strap, supported host interface, operating-temperature range, and management feature between the original and proposed replacement. In particular, the KSZ8563RNXV listing includes I2C and SPI, while the KSZ9563RNXI-TR belongs to a different switch family. Complete manufacturer-level pin and functional validation before substitution.
