DP83630SQ/NOPB - IEEE 1588 Ethernet PHY | Texas Instruments
부품 번호: DP83630SQ/NOPB ✓ 활성DP83630SQ/NOPB 개요
An Ethernet PHY is a physical-layer interface that converts digital data from a MAC or microcontroller into electrical Ethernet signals and converts received signals back into digital data. The DP83630 family integrates IEEE 1588 precision-time-protocol functionality with a 10/100 Ethernet PHY, placing clock synchronization and network communication in one device.
The device provides a single 10/100 Ethernet port and supports both MII and RMII host interfaces. These interfaces give designers flexibility when connecting the PHY to a microcontroller, field-programmable gate array, or dedicated Ethernet controller. The 3.3 V operating supply is compatible with modern embedded systems, while the 48-WQFN package supports compact surface-mount PCB construction.
Integrated IEEE 1588 functionality is the central technical feature of the DP83630 family. According to the Texas Instruments DP83630 datasheet, the device supports precision clock synchronization for real-time industrial connectivity and offers deterministic, low-latency operation without requiring hardware customization of the selected microcontroller. This makes it especially relevant to synchronized measurement, industrial control, factory automation, and communications systems.
Typical applications include industrial Ethernet controllers, factory automation equipment, synchronized data-acquisition systems, networked sensors, communications equipment, and embedded platforms requiring a compact 10/100 PHY with precision-time support. The MII interface supports designs that need individual control and status signals, while RMII can reduce the number of parallel host-interface signals on designs where pin count is constrained.
PCB implementation should use the manufacturer pinout and layout guidance, especially for the exposed pad, magnetic-interface components, crystal or clock network, and high-speed differential pairs. Keep the Ethernet differential routing controlled and provide the specified input, output, and decoupling capacitance close to the relevant device pins.
This product page combines the official device description with package and interface details, application-oriented engineering guidance, and a constraint-aware comparison of directly relevant family parts. It also distinguishes true same-footprint replacements from alternatives that require a different package or PCB redesign.

일반적인 애플리케이션
DP83630SQ/NOPB 적합 용도: 6 애플리케이션s: Synchronized Industrial Automation, Precision Data Acquisition, Factory Sensor Networking, Real-Time Communications Equipment, Networked Test and Measurement, Embedded Industrial Gateway.
Synchronized Industrial Automation
The DP83630SQ/NOPB fits industrial automation equipment that must exchange 10/100 Mbps Ethernet data while maintaining coordinated timing between controllers and field equipment. Its IEEE 1588 precision-time functionality supports deterministic, low-latency synchronization, while the MII or RMII interface allows connection to the selected controller architecture. Using one PHY for network communication and clock synchronization reduces the need for separate timing hardware. The 48-WQFN 7 x 7 mm package also supports compact control boards, although the final layout must preserve the differential Ethernet routing and exposed-pad thermal requirements.
추천
Precision Data Acquisition
The DP83630SQ/NOPB is appropriate for distributed measurement systems in which each node must timestamp or coordinate samples against a common time reference. The device combines a 10/100 Mbps Ethernet PHY with IEEE 1588 synchronization in one 3.3 V package, allowing data to be transported over standard Ethernet while timing is maintained across the network. Its deterministic, low-latency behavior is valuable when acquisition events must be compared across multiple instruments or machines. Designers should follow the manufacturer layout requirements for clocking, magnetic-interface components, and signal integrity.
추천
Factory Sensor Networking
The DP83630SQ/NOPB can connect factory sensors and gateways requiring both network traffic and precise event timing. Its 10/100 Mbps rate supports conventional industrial Ethernet traffic, while IEEE 1588 provides the timing foundation required to correlate sensor readings or control events across machines. The MII option suits controllers with abundant parallel I/O, and RMII helps conserve host pins in compact gateways. The device should be paired with an Ethernet magnetic interface and implemented according to the Texas Instruments recommended layout to maintain signal and thermal performance.
추천
Real-Time Communications Equipment
The DP83630SQ/NOPB fits communications equipment where synchronized endpoints reduce timing uncertainty during message exchange. Its integrated IEEE 1588 capability complements a 10/100 Mbps Ethernet channel, while the MII and RMII host options make it adaptable to different processor interfaces. The 3.3 V supply is suitable for embedded communications platforms, and the 48-WQFN package permits a compact implementation. A key design consideration is separating the timing network requirements from ordinary packet traffic and validating synchronization behavior across the complete network topology.
추천
Networked Test and Measurement
The DP83630SQ/NOPB is suitable for test and measurement instruments that need a standard Ethernet connection plus precise synchronization across distributed test nodes. The 10/100 Mbps PHY provides the data path, while IEEE 1588 timing supports coordinated stimulus, sampling, and result capture. This combination can simplify architectures compared with using an unsynchronized Ethernet PHY and a separate clock-distribution implementation. The MII interface may be preferred for deterministic parallel signaling, whereas RMII can reduce host pin requirements. Board-level clock quality and Ethernet return-loss performance remain critical design details.
추천
Embedded Industrial Gateway
The DP83630SQ/NOPB can serve as the Ethernet physical layer in an embedded industrial gateway that forwards data to a controller or cloud-connected edge system. Its single 10/100 Mbps port, 3.3 V operation, and selectable MII or RMII interface make it adaptable to compact embedded hardware. IEEE 1588 support adds value when upstream devices and internal tasks require coordinated timestamps or deterministic scheduling. The WQFN footprint reduces board area, but designers must provide adequate exposed-pad thermal treatment and closely placed decoupling for reliable operation.

설계 노트
Use the Texas Instruments DP83630 datasheet pin configuration and recommended layout as the authority for all 48-WQFN connections. Place the input, output, and bypass capacitors specified for stability and filtering close to their associated pins. Connect the exposed pad to the required ground and thermal-copper structure, and preserve the manufacturer-defined spacing around the magnetic-interface network.
Route the Ethernet differential pair as a controlled-impedance, tightly coupled pair with minimal vias and no stubs. Keep the PHY and magnetics positioned according to the recommended reference layout because magnetics placement strongly affects return loss and radiated emissions. Review board stack-up, connector geometry, and component tolerances before treating the 10/100 Mbps channel as production-ready.
Do not select a substitute solely because its Ethernet data rate and host interface appear similar. IEEE 1588 support, the 48-WQFN footprint, exposed-pad connection, clock architecture, and all 48 pin assignments must match before a device qualifies as a drop-in replacement. DP83630SQE/NOPB is the closest identified family option, but its complete ordering-code conditions should still be checked against the production requirements.
