KSZ8001S-TR - 10/100 Ethernet PHY | Microchip | SSOP-48 (Tape & Reel)

An Ethernet physical-layer transceiver, or Ethernet PHY, is the circuit that converts digital Ethernet data into signals suitable for twisted-pair or fiber links and converts received signals back into digital data. In the networking hierarchy, the KSZ8001S-TR sits between a Media Access Controller or Ethernet MAC and its physical medium. Its MII, Reduced MII, and Serial MII interfaces provide host-connection choices for embedded systems, industrial controllers, and networking equipment.
Key verified features include 10BASE-T, 100BASE-TX, and 100BASE-FX support, operation from a 1.8 V core, compatibility with 3.3 V signaling, and the three listed host interfaces. The manufacturer literature describes approximately 250 mW power consumption, LinkMD cable-length determination to 200 m with stated accuracy of ±2 m, and robust operation over standard cables longer than 130 m. These characteristics make the device suitable where copper and fiber PHY support share one package.
Technically, the transceiver integrates transmit and receive DSP functions needed for Manchester-coded 10 Mb/s Ethernet and MLT-3 100 Mb/s links. Full MII exposes parallel timing and data signals, RMII reduces pin count for higher-throughput controllers, and SMII provides a serial controller option. The serial management interface enables configuration, while LinkMD assists commissioning by estimating cable length and identifying wiring faults rather than requiring every fault to be diagnosed by a higher-level host.
Typical uses include industrial Ethernet controllers, embedded gateways, test equipment, print servers, network switches, and optical-to-copper interface equipment. A copper-only design can select 10BASE-T or 100BASE-TX links, while 100BASE-FX support can extend the PHY into fiber-oriented designs. Fiber magnetics, optical signaling requirements, and system timing still need validation against the complete interface design.
A key design consideration is that the KSZ8001S-TR needs both its 1.8 V core rail and appropriate 3.3 V analog or digital supplies. Place required bypass capacitors at their pins, route high-speed and analog signals according to the reference layout, and isolate noisy switching nodes from PHY inputs. Check the complete pinout and operating limits in the official KSZ8001L/S datasheet before layout release.
This page consolidates verified distributor information, manufacturer technical capabilities, sourcing context, and engineering guidance. It also distinguishes confirmed KSZ8001S-TR facts from values that still require datasheet validation, avoiding unsupported package, pricing, temperature, or replacement claims.

典型应用
KSZ8001S-TR 适用于 6 应用s: Industrial Ethernet Controller, Copper-Fiber Network Gateway, Embedded Network Terminal, Network Test Equipment, Print and Network Adapter, Fiber-to-Copper Network Interface.
Industrial Ethernet Controller
The KSZ8001S-TR fits an industrial Ethernet controller that may operate over both 10BASE-T and 100BASE-TX copper links. Its 1.8 V core aligns with low-voltage digital systems, while the documented 3.3 V signaling level supports conventional PHY interfaces. Select MII, RMII, or SMII according to the controller resources, and use LinkMD to help identify cabling faults during commissioning. Before production, verify the device's unspecified temperature and EMC requirements against the complete industrial system specification.
推荐
Copper-Fiber Network Gateway
The KSZ8001S-TR is appropriate for a gateway that presents a common PHY interface while supporting 10BASE-T, 100BASE-TX, and 100BASE-FX media. The copper path can serve standard installations, while 100BASE-FX supports fiber-oriented links. The 250 mW power-consumption figure cited in manufacturer literature helps when budgeting an always-on network node. A complete design must still include suitable magnetics or an optical interface and must validate signal integrity for the chosen physical medium.
推荐
Embedded Network Terminal
Use KSZ8001S-TR in an embedded terminal when the host processor lacks native Ethernet media access and requires a dedicated PHY. RMII can reduce the connection burden relative to a full parallel MII when the host supports the required 100 Mb/s signaling, while MII remains available for lower-rate or timing-compatible controllers. The documented 1.8 V core is useful for compact embedded systems, but supply sequencing, I/O voltage, and exact MAC timing must be confirmed from the official datasheet.
推荐
Network Test Equipment
KSZ8001S-TR can support portable or benchtop Ethernet test equipment that needs selectable copper or fiber physical media. LinkMD's cable-length measurement up to 200 m and stated ±2 m accuracy adds installation-oriented diagnostic value, while MII, RMII, and SMII permit testing different controller-facing configurations. Reported power consumption of approximately 250 mW supports compact portable systems. Measurement accuracy, startup behavior, and interface limits should be verified in the final test architecture.
推荐
Print and Network Adapter
The KSZ8001S-TR can serve as the Ethernet physical layer in a print-server or network-adapter design requiring 10 Mb/s and 100 Mb/s operation. Copper compatibility supports conventional office links, while 100BASE-FX provides a path for longer-distance fiber installations. The host interface should be selected to match the embedded controller's bus and clock architecture. Component count and power remain favorable for a dedicated PHY approach, but protocol firmware, transformer interfaces, isolation, and physical-layer compliance still require system-level validation.
推荐
Fiber-to-Copper Network Interface
KSZ8001S-TR is suited to equipment that translates between 100BASE-FX fiber and 10/100 Mb/s copper-facing Ethernet interfaces. Supporting all three listed PHY media in one device simplifies product-family commonality and gives integrators a consistent host-interface set. The manufacturer-reported 250 mW consumption is a useful starting point for thermal budgeting, but actual use depends on operating mode and supply implementation. Validate optical component selection, isolation, and timing against the official application guidance.

设计说明
Follow the official KSZ8001L/S reference layout and keep the 1.8 V core, 3.3 V analog, and digital-supply bypass connections short and local. Preserve the indicated ground and signal-return paths around transmit, receive, and clock pins. Because MII, RMII, or SMII operation changes which signals are active, freeze interface selection before final routing and review every unused PHY connection against the official pin table.
Treat clocks, serial management signals, and the selected MII, RMII, or SMII interface as timing-sensitive connections. Use the manufacturer's recommended termination and impedance guidance, keep clock traces away from noisy switching nodes, and match interface characteristics to the Ethernet controller. Validate eye timing and margin at the actual board speed; do not infer compatibility solely from the shared MII or RMII label.
Budget the manufacturer-reported approximately 250 mW KSZ8001S-TR consumption, plus magnetics, host circuitry, and board-level conversion losses. The PHY uses a 1.8 V core and 3.3 V signaling, so supply sequencing and rail noise can affect system behavior. Confirm each supply's tolerance, startup requirement, and decoupling value in the official datasheet; no exact capacitor values were present in the verified snippets.
Do not treat KSZ8001S-TR, KSZ8001S-TRI, KSZ8001L, and KS8001S as interchangeable without comparing their complete pin and electrical tables. The verified search results establish related family identities but do not prove identical lead functions, temperature grades, or interface limits. Check errata, supply requirements, copper/fiber support, and host timing before approving any suffix substitution for an existing 48-pin SSOP layout.
合规信息
The verified search results do not extract RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. KSZ8001S-TR is an Ethernet interface IC, so automotive qualification through AEC-Q100 is not indicated by the supplied evidence.
