KSZ8463MLI - 3-Port 10/100 Managed Ethernet Switch | Microchip
部品番号: KSZ8463MLI ✓ 生産中KSZ8463MLI 概要
An Ethernet switch is a network-semiconductor device that connects multiple Ethernet nodes while forwarding frames according to learned or configured addresses. The KSZ8463 belongs to the managed-switch and Ethernet-interface hierarchy: it combines three 10/100 Ethernet ports with a media-independent interface for connection to a host processor or communications controller. This integration can reduce the number of separate network components required in industrial gateways, motion controllers, test equipment, and synchronized automation systems.
The device supports IEEE 1588v2-enabled synchronization and provides an MII interface. Its three 10/100 ports operate at data rates up to 100 Mbps, while the 64-LQFP package provides 64 pins in a 10 x 10 mm surface-mount format. The verified source data identifies 1.8 V, 2.5 V, and 3.3 V supply-voltage options and an operating-temperature maximum of 85 C.
The KSZ8463MLI combines local Ethernet switching with precision-time information in one device. This makes it applicable where ordinary Ethernet connectivity must coexist with accurate timing across industrial nodes. Its MII host connection supports integration with an embedded processor or dedicated communications controller, while the integrated switch reduces the external switching component count.
Typical uses include Industrial Ethernet gateways, factory automation controllers, synchronized test and measurement systems, communications equipment, and embedded industrial networks. Engineers should verify the complete electrical limits, clocking requirements, media interface details, and management configuration against the manufacturer datasheet before releasing a production PCB.
A critical design consideration is that IEEE 1588 synchronization depends on accurate clock distribution and carefully implemented network timing. The MII timing, PHY magnetics, termination, decoupling, and board-level isolation must therefore be reviewed together rather than treated as independent blocks. This page combines verified manufacturer and distributor information, sourcing guidance, application context, and honest replacement analysis.

主な用途
KSZ8463MLI の用途: 6 件s: Industrial Ethernet Gateway, Precision Time Protocol Test Equipment, Factory Automation Controller, Synchronized Motion Control Node, Communications Equipment, Network Monitoring Appliance.
Industrial Ethernet Gateway
The KSZ8463MLI fits an Industrial Ethernet gateway that must consolidate several 10/100 endpoints while preserving timing information for synchronized equipment. Its three 10/100 ports reduce the need for separate switch devices, and the MII interface provides a defined connection to an embedded host processor. IEEE 1588v2 support is particularly useful when downstream machines exchange time-sensitive operational data. The 64-LQFP 10 x 10 mm package supports compact controller boards, although verified thermal, clocking, magnetic-component, and isolation details must be checked against the manufacturer datasheet before layout release.
おすすめ
Precision Time Protocol Test Equipment
The KSZ8463MLI is appropriate for test and measurement systems that must combine Ethernet communication with IEEE 1588v2 synchronization. The three-port 10/100 switch allows local test nodes, controllers, and service interfaces to share one network section, while the MII host interface supports a processor-based instrument controller. IEEE 1588 capability makes the device more suitable than a basic switch for systems where event timing must be coordinated across distributed equipment. Designers should preserve clean clocking paths, validate the required timing accuracy, and confirm the complete electrical and management configuration from the manufacturer documentation.
おすすめ
Factory Automation Controller
The KSZ8463MLI can serve as the switched Ethernet and timing node in a factory automation controller connected to sensors, drives, remote I/O, or line-side equipment. Its three 10/100 ports support multiple 100 Mbps network nodes, while MII integration allows the controller processor to manage traffic and timing functions. IEEE 1588v2 synchronization is useful where coordinated motion or process events must share a time reference. Industrial suitability depends on the complete operating specification, environmental requirements, and network topology. Isolation, surge protection, robust magnetics, and grounding should be designed according to the application’s electromagnetic and safety requirements.
おすすめ
Synchronized Motion Control Node
The KSZ8463MLI fits a distributed motion-control node that must communicate over 10/100 Ethernet while maintaining coordinated timing between drives or controllers. Three integrated ports can connect the local processor, an upstream network segment, and a field endpoint without a separate basic switch. The IEEE 1588v2 capability supports distributed clock synchronization, while MII supplies a host-side interface. For a production design, engineers must verify jitter performance, clock-source configuration, recovery behavior, and cable or fiber media requirements from the datasheet rather than assuming synchronization accuracy from the feature label alone.
おすすめ
Communications Equipment
The KSZ8463MLI is suitable for embedded communications equipment requiring three local 10/100 network connections and a processor-facing MII interface. A management or edge-communication box can use the switch portion for port concentration while retaining the possibility of IEEE 1588-aware timing when connected equipment participates in a synchronized network. The surface-mount 64-LQFP package avoids through-hole assembly and keeps the device practical for compact embedded platforms. Designers must confirm address-table limits, management features, supported media, and host-driver expectations in the datasheet, and should plan Ethernet magnetics, line protection, and chassis-grounding for the target installation.
おすすめ
Network Monitoring Appliance
The KSZ8463MLI can support a compact network-monitoring appliance that gathers traffic or status from multiple 10/100 Ethernet nodes. Its three ports provide a local switching fabric, while the MII host interface allows an embedded processor to observe or manage network activity. IEEE 1588v2 support is beneficial when monitoring systems require correlated timing among test points or machines. The chosen 64-LQFP package supports automated surface-mount assembly and compact board layouts. Deployment still requires validation of port statistics, management access, timing precision, maximum frame handling, and environmental limits against the manufacturer documentation before the design is released for manufacturing.

設計ノート
Place the KSZ8463MLI and its decoupling capacitors near the associated supply pins, with the ground-return path kept short and continuous. Ethernet PHY and magnetics placement should follow the manufacturer’s reference layout so differential pairs remain controlled and isolated from switching or high-current circuitry. Do not finalize the 64-pin assignment until the official pin diagram has been cross-checked against the selected MII and clocking configuration.
Treat the MII clock and Ethernet differential signals as controlled-impedance nets, and keep them away from noisy power converters and digital clocking sources. The device’s IEEE 1588v2 capability does not eliminate the need for a clean reference clock, correctly terminated media interface, and verified network topology. Review rise-time, jitter, trace length, return paths, and connector or magnetics requirements using the manufacturer’s electrical and layout guidance before production release.
Confirm the required 1.8 V, 2.5 V, or 3.3 V supply option and associated digital-interface voltage levels before schematic capture. Because the verified data does not provide current consumption or regulator recommendations, use the manufacturer datasheet for operating and maximum current, power-up sequencing, and decoupling values. Do not reuse a generic 1.2 V or 1.8 V rail without confirming compatibility with the selected device configuration.
Do not treat KSZ8463MLI and KSZ8463MLI-TR as different functional replacements; the latter is a tape-and-reel ordering option. Likewise, a generic three-port Ethernet switch is not automatically interchangeable because MII pin assignment, management behavior, IEEE 1588v2 support, media implementation, and software-driver expectations may differ. Verify complete pin compatibility and timing functionality before approving any replacement.
コンプライアンス情報
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer or package family.
