KSZ8061MNGW - 100Mbps Ethernet PHY | Microchip | 48-QFN
MPN: KSZ8061MNGW ✓ فعالKSZ8061MNGW نمای کلی
An Ethernet physical-layer transceiver, commonly called an Ethernet PHY, converts digital data into electrical signaling for a wired network and receives and restores incoming signals. Within the network hierarchy, the KSZ8061MNGW sits between a digital Ethernet controller or processor and the transformer-coupled line interface. The KSZ8061 family supports 10BASE-T and 100BASE-TX operation and includes Microchip Quiet-WIRE internal filtering intended to reduce line noise.
The principal specifications include support for 10 Mb/s and 100 Mb/s operation, a 3.135 V to 3.465 V operating-supply range, and compatibility with 1.8 V, 2.5 V, and 3.3 V signaling environments listed for the device. Quiet-WIRE internal filtering is a notable family-level feature for reducing unwanted network-line noise. The 48-QFN construction also includes an exposed pad according to the package description, supporting compact PCB layouts and improved heat spreading when the land pattern is implemented correctly.
Microchip describes the KSZ8061 as a family of single-chip 10BASE-T and 100BASE-TX physical-layer transceivers. Internal wave shaping and pre-emphasis are used by its 10BASE-T drivers, while the 100BASE-TX path supports copper cabling through an appropriate magnetic interface. These functions allow an Ethernet-capable processor, media-access controller, or communications controller to connect to 10BASE-T or 100BASE-TX networks without implementing the complete analog line interface externally.
Typical applications include embedded Ethernet links for industrial controllers, building-automation equipment, consumer electronics, communications equipment, and network-interface modules. The device is particularly relevant when a design requires 100BASE-TX connectivity and a compact 48-QFN footprint. System-level implementation still requires correct magnetic-device selection, controlled-impedance routing, solid grounding, and separation between sensitive analog and digital circuitry.
A key design consideration is the exposed thermal pad beneath the 48-QFN package. Follow the manufacturer land-pattern guidance for thermal-via placement and connect the pad to the appropriate ground plane. Decoupling capacitors should be located close to the supply pins, while differential and line-side routing should follow the application guidance associated with the magnetic device.
This product page consolidates the manufacturer-family description, exact package and operating information, sourcing details, application guidance, and verified drop-in alternatives. It is designed to help engineers compare Ethernet PHY options while preserving the distinction between electrical compatibility, package compatibility, and a genuine pin-to-pin replacement.

کاربردهای معمول
KSZ8061MNGW مناسب است برای 6 کاربردs: Industrial Ethernet Controller, Building Automation Gateway, Communications Equipment, Embedded Network Interface Module, Consumer Network Appliance, Test and Measurement Instrument.
Industrial Ethernet Controller
The KSZ8061MNGW fits an embedded controller that must connect to a 10BASE-T or 100BASE-TX network through a qualified magnetic interface. Its 100 Mb/s maximum rate supports factory automation, environmental monitoring, and building-control equipment, while the 3.135 V to 3.465 V supply range suits 3.3 V power architectures. Use the exposed-pad land pattern for thermal-via placement, place local bypass capacitors at the supply pins, and confirm that the host controller supports the PHY's register, clocking, and reset requirements before schematic capture.
پیشنهادی
Building Automation Gateway
The KSZ8061MNGW can provide the wired Ethernet physical layer for HVAC controllers, room modules, access-control terminals, and energy-management gateways. Supporting both 10 Mb/s and 100 Mb/s allows the equipment to remain compatible with legacy 10BASE-T infrastructure while using 100BASE-TX on faster networks. The 48-QFN, 7 mm by 7 mm package preserves board area, and Quiet-WIRE internal filtering can reduce line noise. The layout must still separate line-side and digital paths and use the manufacturer's exposed-pad construction.
پیشنهادی
Communications Equipment
A communications terminal, protocol converter, or serial-to-Ethernet appliance can use the KSZ8061MNGW as the copper network interface. Its 100 Mb/s capability is appropriate for management traffic and industrial data links, while 10BASE-T compatibility supports legacy infrastructure. The device's 3.135 V to 3.465 V operating range aligns with common 3.3 V system rails, and the exposed pad helps spread heat when implemented with the correct via pattern. Qualification should include cable insertion, startup sequencing, reset behavior, and temperature testing across the intended product envelope.
پیشنهادی
Embedded Network Interface Module
The KSZ8061MNGW is suitable for compact embedded Ethernet interface modules that connect a processor or microcontroller-oriented controller to twisted-pair networks. Supporting 10BASE-T and 100BASE-TX provides flexibility between older and faster links, and the 48-QFN footprint limits board area in space-constrained systems. Its Quiet-WIRE filtering feature can improve network-line behavior without a conventional external filtering arrangement. The system integrator must still select a compatible magnetic device, follow the recommended line-side layout, and verify host-side timing and signal levels.
پیشنهادی
Consumer Network Appliance
The KSZ8061MNGW can serve as the 10BASE-T/100BASE-TX interface in a consumer gateway, smart-home controller, media bridge, or network accessory. The 100 Mb/s rate is suitable for local management and control traffic, and the compact 48-QFN package supports dense consumer-electronics layouts. Quiet-WIRE filtering helps reduce unwanted line noise in shared industrial environments where products may also connect to office networks. Production validation should cover recovery from cable faults, power cycling, link negotiation, and operation with the intended magnetic component and enclosure grounding system.
پیشنهادی
Test and Measurement Instrument
The KSZ8061MNGW can provide network connectivity for automated test equipment, data loggers, and portable measurement instruments that exchange data over copper Ethernet. A 100 Mb/s link offers sufficient throughput for instrument control and moderate measurement data, while 10BASE-T support enables connection to older test networks. Its 48-QFN package and exposed pad suit compact instrument boards, but the thermal and grounding layout remain important. Use controlled-impedance routing, follow the magnetic-device layout, and verify conducted and radiated emissions before production release.

یادداشت‌های طراحی
Implement the 48-QFN exposed pad as a thermal and electrical land pattern rather than leaving it unsoldered. Place a compact array of thermal vias directly beneath the pad and connect the pad to the intended ground plane using the manufacturer's package guidance. The via arrangement should balance heat spreading with unwanted inductance, and the copper area around the package should be evaluated under the highest expected ambient temperature and sustained network activity.
Place the PHY bypass capacitors close to their associated supply pins, with the shortest practical ground-return paths. Follow the manufacturer reference layout for the digital interface and the selected magnetic device, and route high-current or line-side connections away from sensitive clock and control signals. Controlled-impedance routing is important for digital and analog interfaces even though the KSZ8061MNGW itself targets the relatively low 10 Mb/s and 100 Mb/s Ethernet rates.
Do not treat every 100 Mb/s Ethernet PHY as a pin-compatible substitute for the KSZ8061MNGW. Before replacing it, compare the 48-QFN pad layout, pin names, supply limits, I/O levels, clock source, reset sequence, strap options, register map, and exposed-pad connection. The Quiet-WIRE filtering behavior and 10BASE-T wave-shaping functions are also family-specific considerations that should be reviewed during second-source qualification.
Keep the Ethernet line-side section compact and follow the layout associated with the qualified magnetic device. Maintain continuous ground references, avoid routing line-side signals beneath split or poorly bonded ground regions, and provide the intended enclosure or chassis termination path. EMI performance should be verified in the final product because cable construction, shielding, power-supply layout, and enclosure construction can materially change radiated and conducted emissions.
