KSZ8061RNDW - 10/100 Ethernet PHY | Microchip | 32-QFN
MPN: KSZ8061RNDW ✓ فعالKSZ8061RNDW نمای کلی
An Ethernet physical-layer transceiver, or Ethernet PHY, converts digital data into signals suitable for twisted-pair cabling and recovers digital data from received signals. In the system hierarchy, the PHY connects a network medium interface to an Ethernet MAC or controller. KSZ8061RNDW belongs to the 10/100 Ethernet PHY category within interface ICs, rather than operating as a general-purpose transceiver or a complete Ethernet controller.
The key specified features are support for 10BASE-T and 100BASE-TX, one Ethernet transceiver channel, a 3.3 V supply, and a compact 32-QFN EP package. Quiet-WIRE filtering is a significant family-level feature because it is intended to reduce cable-side emissions and improve robustness against environmental interference. The exposed pad supports thermal transfer when the device is soldered to an appropriately designed ground plane, although exact thermal and electrical limits must be confirmed from the manufacturer datasheet before design release.
The KSZ8061 integrates the physical-layer functions required to communicate with a 10BASE-T or 100BASE-TX network medium. These functions include signal transmission, reception, line coding, and cable-side filtering. Its 5 mm by 5 mm package supports space-constrained industrial and embedded equipment while exposing a thermal and electrical path through the EP. Design engineers must follow the manufacturer's hardware checklist for magnetics, termination, layout, decoupling, and exposed-pad implementation.
Typical applications include industrial Ethernet controllers, embedded control systems, factory automation equipment, network adapters, print servers, and compact communication modules. The device is appropriate where a system requires a single 10/100 copper-Ethernet port rather than multi-gigabit operation. For new designs, verify the required cable category, auto-negotiation behavior, isolation requirements, regulator tolerance, and environmental temperature range against the complete manufacturer documentation.
The principal PCB concern is preserving the controlled impedance and symmetry of the differential transmit and receive pairs. Place the PHY, magnetics, supporting passives, and the Ethernet connector according to the Microchip hardware design checklist, with particular attention to return paths and exposed-pad grounding. Avoid substituting package or suffix variants without checking the ordering code, temperature range, tape-and-reel configuration, and pin-compatible application requirements.
This page combines manufacturer product information, package identification, interface-function details, engineering guidance, and qualified drop-in alternatives. It also highlights the verification points that separate a nominal Ethernet PHY match from a production-ready replacement, including pin compatibility, electrical parameters, packaging, thermal implementation, and lifecycle status.

کاربردهای معمول
KSZ8061RNDW مناسب است برای 6 کاربردs: Industrial Ethernet Control Systems, Embedded Network Adapters, IoT Gateways and Edge Devices, Network Print and Storage Appliances, Building and Security Controllers, Test and Measurement Equipment.
Industrial Ethernet Control Systems
The KSZ8061RNDW fits a single-port 10/100 Ethernet interface in PLCs, industrial controllers, remote I/O modules, and factory automation equipment. Its stated 10 Mb/s and 100 Mb/s operation covers legacy and common industrial network segments, while the 3.3 V supply integrates with modern embedded controller rails. Quiet-WIRE internal filtering is intended to reduce cable-side noise in electrically active environments. Use the manufacturer hardware checklist to place the PHY, magnetics, ESD protection, and connector as one controlled signal chain, and verify the selected ordering code's temperature range for the required ambient conditions.

Embedded Network Adapters
KSZ8061RNDW provides the copper-Ethernet physical layer for embedded Linux, real-time controller, and appliance designs that require one 10/100 port. The 32-QFN EP package reduces board area compared with larger transceivers, and the 3.3 V operating point suits modern host processors. Designers connect the PHY to an Ethernet MAC or controller using the manufacturer's interface and pin assignments. Differential routing, magnetics selection, impedance control, and exposed-pad grounding remain critical because a physically compact package does not remove Ethernet signal-integrity requirements.
پیشنهادی
IoT Gateways and Edge Devices
The KSZ8061RNDW is suitable for compact IoT gateways, edge computers, and connected equipment requiring wired Ethernet rather than a wireless-only interface. A 10/100 PHY can coexist with higher-speed internal processing while providing a straightforward management or service connection. The single-channel configuration avoids unused PHY circuitry, and Quiet-WIRE filtering supports cleaner cable-side operation in shared equipment environments. Keep the Ethernet channel physically separated from switching regulators, high-speed memory, and radiating interfaces, and follow the hardware checklist for transformer, termination, and connector implementation.

Network Print and Storage Appliances
KSZ8061RNDW can provide the 10/100 network port in print servers, scanners, storage controllers, and other compact appliances whose installed network infrastructure supports Fast Ethernet. Its one-channel 10BASE-T/100BASE-TX function is sufficient for a dedicated management or data port. The 3.3 V supply and 5 mm by 5 mm QFN EP package support compact board layouts, while the exposed pad provides a direct thermal path when the board offers adequate copper area. Production validation should cover link auto-negotiation, transformer selection, return loss, radiated emissions, and fault behavior across the intended cable network.
پیشنهادی
Building and Security Controllers
The KSZ8061RNDW can add a wired management link to access-control panels, building controllers, security equipment, and environmental monitoring systems. Quiet-WIRE internal filtering helps reduce cable-side noise, which is useful where the Ethernet cable runs near motors, relays, or switching power supplies. The 3.3 V device can operate from a regulated embedded rail, and its compact package preserves board area for sensing and actuator circuitry. Maintain controlled differential impedance, use the prescribed magnetics and ESD arrangement, and isolate noisy switching nodes to preserve Ethernet signal quality.
پیشنهادی
Test and Measurement Equipment
KSZ8061RNDW fits Ethernet-enabled test instruments, communication analyzers, and laboratory devices requiring a single 10/100 copper port for control or data transfer. The PHY family provides transmission and reception over unshielded twisted-pair cable, with Quiet-WIRE internal filtering for cable-side noise reduction. Designers should treat the differential pair as a controlled-impedance structure and place the PHY close to the magnetic components and connector. Validate the complete channel for insertion loss, return loss, radiated emissions, and susceptibility under the actual instrument enclosure and external cabling conditions.

یادداشت‌های طراحی
Use the Microchip KSZ8061RND Hardware Design Checklist as the controlling layout document. Route the transmit and receive differential pairs as controlled-impedance structures, preserve symmetry between each pair, provide continuous ground references, and minimize vias. Keep the PHY-to-magnetics path short and place the magnetic device and connector according to the reference implementation rather than improvising a shorter but electrically incompatible arrangement.
Follow the manufacturer requirements for 3.3 V supply decoupling and exposed-pad grounding. Place the required ceramic capacitors close to their designated power pins and connect the exposed pad to the ground plane with a low-impedance path. Check capacitor voltage rating, DC-bias characteristics, and placement against the latest datasheet. Do not assume that the package's EP can substitute for every internal ground connection.
Treat the Ethernet cable-side network as a controlled RF structure even at 100 Mb/s. Use the specified magnetics and termination arrangement, keep the connector and magnetics interfaces free of uncontrolled stub lengths, and maintain separation from switching-regulator paths and high-current digital returns. Validate insertion loss, return loss, radiated emissions, and link stability with the intended cable and enclosure rather than relying only on eye-pattern measurements at the PHY.
Do not treat a shared package or the 10/100 label as sufficient proof of drop-in compatibility. Verify pin names and functions, supply levels, timing, reset behavior, clock requirements, temperature grade, exposed-pad construction, and ordering options against the manufacturer documentation. In particular, KSZ8061RNDW, KSZ8061RNDW-TR, KSZ8061MNXI, and KSZ8061RNDV-TR have different ordering suffixes whose commercial and temperature implications must be checked before substitution.
