KSZ8041TL 10/100 Ethernet PHY | Microchip | TQFP-48
MPN: KSZ8041TL ✓ Hoạt độngKSZ8041TL Tóm tắt
An Ethernet physical-layer transceiver, or PHY, converts digital MAC data into signals suitable for twisted-pair cabling and converts received cable signals back into digital data. The KSZ8041 belongs to the Ethernet interface IC hierarchy, connecting a network media-access controller to a 10BASE-T or 100BASE-TX copper link. Its MII, RMII, and SMII support lets designers select an interface appropriate to the host controller and board constraints.
The KSZ8041TL provides separate 10BASE-T and 100BASE-TX operation, automatic cable-related handling, and support for HP Auto MDI/MDIX according to the Microchip product page. These features simplify connection to standard Ethernet magnetics and network transformers without requiring a fixed transmit/receive crossover configuration. The verified sources also describe the KSZ8041TL as a low-power physical-layer solution enabled by a mixed-signal architecture.
The manufacturer datasheet describes INTRP on pin 32 as an optional interrupt signal for informing an external controller that the PHY register has received a status update. This makes the device suitable for designs requiring PHY-status monitoring alongside packet transmission and reception. The digital host interface can be used with controllers that support MII, RMII, or SMII, subject to the voltage, timing, and pin requirements in the device documentation.
Typical uses include industrial Ethernet controllers, embedded gateways, printers, set-top equipment, network interface cards, media-conversion equipment, and industrial control systems. The TL variant is intended for copper-based 10BASE-T/100BASE-TX links; the related KSZ8041FTL adds 100BASE-FX support, so it is not a drop-in functional substitute unless the PCB and magnetics are specifically designed for fiber.
For a new layout, follow the manufacturer pinout and reference-circuit recommendations exactly, especially the supply bypass capacitors, crystal or clock network, Ethernet differential pairs, and isolation or magnetics interface. Keep the digital MII/RMII/SMII traces away from the analog magnetics-side circuitry, maintain the specified impedance environment, and provide clean power referenced to the device ground. Confirm the exact package variant, temperature range, and ordering suffix before releasing a PCB.

Ứng dụng tiêu biểu
KSZ8041TL phù hợp cho 6 Áp dụngs: Industrial Ethernet Gateway, Network Interface Card, Embedded Printer Controller, Set-Top Box Network Port, Industrial Control Terminal, Media and Network Appliance.
Industrial Ethernet Gateway
The KSZ8041TL fits an embedded gateway that bridges a host processor to a 10BASE-T or 100BASE-TX copper link. Its MII, RMII, and SMII options allow the PCB designer to match the controller interface and reduce unnecessary digital wiring. The PHY handles the physical Ethernet signaling layer while the MAC and application processor manage framing, routing, and protocols. Its mixed-signal architecture is intended to support extended signaling distance with reduced power consumption. Before layout release, verify the exact operating-temperature grade, supply limits, magnetics, isolation, and reference-clock requirements from the Microchip datasheet.
Được đề xuất
Network Interface Card
KSZ8041TL can serve as the physical-layer device in a 10/100 Ethernet network interface card connected to an MII-, RMII-, or SMII-capable controller. The 48-TQFP package supports a compact board implementation, while the copper 10BASE-T/100BASE-TX support covers legacy Fast Ethernet equipment. The PHY-side layout should preserve controlled differential impedances and separation from sensitive digital clocks. Engineers must also confirm whether auto MDI/MDIX operation satisfies the cable and transformer arrangement used by the target NIC rather than assuming every magnetics configuration is interchangeable.
Được đề xuất
Embedded Printer Controller
The KSZ8041TL is suitable for an embedded printer controller that needs Fast Ethernet connectivity alongside a real-time host processor. RMII can reduce the number of digital bus signals compared with a full parallel interface when the host controller supports it, while MII remains available for designs with different timing constraints. The copper PHY handles link signaling, leaving the host responsible for packet processing and print-job traffic. Because the supplied data does not confirm every electrical and timing limit, the controller team should validate clocking, reset, interrupt, magnetics, and isolation directly against the official Microchip documentation.
Được đề xuất
Set-Top Box Network Port
KSZ8041TL can provide the copper Ethernet physical layer for a set-top box or consumer network appliance that connects to a 10/100 Mb/s home or enterprise network. The MII, RMII, and SMII choices provide flexibility across different media-access controllers and board architectures. Its single-supply mixed-signal design is useful where power and board area are constrained, although the exact supply and thermal limits must be confirmed for the selected ordering suffix. Keep the Ethernet magnetics and high-frequency copper traces physically separated from audio, video, and processor power paths to reduce coupling and maintain signal integrity.
Được đề xuất
Industrial Control Terminal
The KSZ8041TL is a reasonable starting point for an industrial control terminal requiring a copper Ethernet uplink and flexible MAC connectivity. The optional INTRP signal can provide an external controller with a PHY-register status indication, which is useful when link state, configuration, or fault handling must be monitored. The final design must verify the exact temperature range, supply tolerance, reset behavior, reference clock, and magnetics isolation requirements. For harsh environments, add appropriately reviewed surge and ESD protection without disturbing the controlled-impedance differential pairs.
Được đề xuất
Media and Network Appliance
KSZ8041TL can be evaluated in a small network appliance that uses a copper Ethernet uplink for configuration, monitoring, or management traffic. The device's 10BASE-T/100BASE-TX support is appropriate for equipment that must interoperate with older Fast Ethernet infrastructure, while MII/RMII/SMII flexibility allows host-controller selection. The PHY is not a complete network processor, so firmware, media access, TCP/IP behavior, and security remain the responsibility of the host system. Use the manufacturer reference circuitry and verify transformer isolation, center-tap handling, and grounding before production release.

Ghi chú thiết kế
Use the manufacturer datasheet reference circuit for the 48-TQFP footprint, Ethernet transformer or magnetics interface, reset, reference clock, and bypass components. Place the PHY and its required support components close to the board connector while keeping the high-speed copper-side differential pairs short, paired, and impedance-controlled. Do not infer exposed-pad connections or thermal requirements from the package name alone.
Separate the PHY magnetics-side nets from MII, RMII, and SMII digital signals, especially clocks and data lines. Route Ethernet differential pairs as a matched pair with no uncontrolled stubs or layer transitions, and provide a continuous reference plane where practical. Any isolation, surge-protection, or ESD network should be validated in the complete channel because adding capacitance can degrade Ethernet signal integrity.
Place the required local bypass capacitors next to the device supply and ground pins, and follow the manufacturer placement and current-loop recommendations exactly. The verified data confirms a single-supply architecture but does not provide the complete capacitor-value and voltage-rating table, so those values must be obtained from the official datasheet. Confirm power sequencing and startup behavior with the host controller before release.
Do not select KSZ8041TL for a design that requires 100BASE-FX merely because the related KSZ8041 family is used. The verified manufacturer snippet states that KSZ8041FTL adds 100BASE-FX support, while KSZ8041TL is identified for copper 10BASE-T/100BASE-TX. Also verify the exact ordering suffix, temperature grade, package pinout, and MII/RMII/SMII mode before substituting a related listing.
Thông tin tuân thủ
The supplied verified snippets do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than being inferred.
