DP83620SQ/NOPB - 10/100 Ethernet PHY | Texas Instruments
料号： DP83620SQ/NOPB ✓ 量产中DP83620SQ/NOPB 概述
An Ethernet PHY transceiver is the physical-layer interface between a digital network controller and copper or fiber media. It converts digital MII or RMII data into electrical signaling for 10BASE-T or 100BASE-TX Ethernet, while handling line coding, link status, collision-related signaling, auto-negotiation, and physical-layer diagnostics. Within the network interface hierarchy, the DP83620 sits between an Ethernet MAC or embedded processor and a transformer-coupled network connection.
The DP83620 supports 10-Mbps and 100-Mbps operation and offers MII and RMII host interfaces. MII provides a parallel 32-bit-style data path, while RMII reduces the required host signals and supports a compact interface implementation. The integrated JTAG support assists hardware configuration and manufacturing test, and the fiber-support feature broadens the PHY's use in industrial networking equipment.
The device includes a 25-MHz clock output, allowing a system to derive a reference clock without requiring an additional oscillator. Its intelligent power-down states reduce consumption when the link is inactive. These features are useful in industrial controllers, embedded platforms, and communications equipment where energy use, diagnostic access, and long-duration field operation are important design considerations.
Typical applications include industrial Ethernet controllers, factory automation equipment, embedded Linux systems, network bridges, serial-to-Ethernet gateways, and optical-network-interface equipment. The 7 x 7 mm WQFN package supports compact designs but requires careful layout of the exposed thermal pad, high-speed traces, supply connections, and magnetic-interface network path.
For a new design, follow the manufacturer datasheet's reference layout and keep the Ethernet differential pairs routed as controlled-impedance pairs with minimal stubs and discontinuities. Confirm magnetics, termination, isolation, thermal performance, and the exact exposed-pad land pattern during PCB implementation.
This page organizes the part's industrial Ethernet features, orderable same-family alternatives, application guidance, package considerations, and design checks into a compact engineering reference. It also identifies where pin assignments, exact power ratings, and detailed electrical limits must be confirmed in the manufacturer documentation.

典型应用
DP83620SQ/NOPB 适用于 6 应用s: Industrial Ethernet Controller, Factory Automation Gateway, Embedded Linux Network Interface, Network-to-Serial Gateway, Fiber-Ready Network Equipment, JTAG-Enabled Manufacturing Test.
Industrial Ethernet Controller
The DP83620SQ/NOPB fits an industrial controller that requires a dedicated 10/100-Mbps Ethernet physical layer alongside an embedded MCU or network processor. Its MII interface supports parallel PHY connectivity, while RMII offers a lower-pin-count option for designs with constrained host I/O. The industrial temperature rating of -40C to 85C suits factory equipment, and the 25-MHz clock output can simplify reference-clock distribution. Designers should verify timing, reset behavior, and the exposed-pad layout against the manufacturer reference design.
推荐
Factory Automation Gateway
A factory automation gateway can use the DP83620SQ/NOPB as its 10/100-Mbps Ethernet uplink when the equipment also supports older copper networks. The PHY's cable-length performance beyond IEEE specifications is valuable in industrial buildings where cable runs and terminations vary. MII or RMII connects the PHY to gateway logic, while the 48-pin 7 x 7 mm WQFN helps limit board area. Proper magnetics, isolation, surge protection, and differential-pair routing remain essential for reliable field operation.
推荐
Embedded Linux Network Interface
The DP83620SQ/NOPB is appropriate for an embedded Linux platform requiring a stable 10/100-Mbps wired-network connection. RMII can reduce host pin usage when the processor supports that interface, and the integrated 25-MHz clock output may reduce clocking complexity. The PHY supports JTAG, which can assist production configuration and test. Software bring-up should confirm PHY address, interrupt behavior, auto-negotiation, and the Linux driver path while the PCB preserves the manufacturer's Ethernet and thermal layout.
推荐
Network-to-Serial Gateway
A serial-to-Ethernet gateway can use the DP83620SQ/NOPB to provide a wired 10/100-Mbps management or control channel without adding a complex multi-port switch. Its industrial-temperature range supports equipment operating from -40C to 85C, and intelligent power-down states can reduce consumption when the network link is inactive. MII or RMII connects the PHY to the gateway processor, while an isolated transformer and magnetics path connect it to the network. Thermal-pad soldering and controlled-impedance differential routing should be validated at board level.
推荐
Fiber-Ready Network Equipment
The DP83620SQ/NOPB's fiber support makes it relevant to network equipment designed around copper Ethernet alongside an optical interface. The PHY handles the 10/100-Mbps physical layer while the system supplies the required media conversion and isolation architecture. Its MII and RMII choices allow reuse across processors with different host-interface resources. The 25-MHz clock output and intelligent shutdown states support compact, power-conscious designs. Confirm the exact fiber-mode implementation, external components, and timing in the manufacturer documentation before schematic release.
推荐
JTAG-Enabled Manufacturing Test
The DP83620SQ/NOPB can support manufacturing-test architectures that use JTAG for configuration, board debug, or production inspection. JTAG is especially useful where access to the Ethernet link is unavailable during initial board bring-up. The PHY connects to the host processor through MII or RMII and to the network through standard magnetics, enabling a test sequence that checks interface communication, clocking, and physical-layer behavior. Test-point access and the exposed-pad layout should be planned without disturbing the high-speed copper and magnetics interface.

设计说明
Route the Ethernet differential pairs as controlled-impedance, tightly coupled traces with no stubs, test pads, or unnecessary layer transitions. Keep the PHY-to-magnetics path short and follow the separation and return-path guidance in the TI DP83620 layout documentation. Place termination, common-mode, and magnetic components at the locations shown in the manufacturer reference layout to preserve cable-length and emissions performance.
The 48-pin WQFN includes an exposed thermal pad that must be soldered according to the manufacturer's land pattern and assembly guidance. Provide adequate ground-via density beneath the pad and a continuous copper connection where permitted. Check the final board's copper area, enclosure airflow, ambient temperature, and power dissipation before treating the package as an adequate heat spreader for the complete design.
Place all PHY supply decoupling capacitors immediately beside their associated power and ground pins, using the manufacturer-recommended capacitance, voltage rating, and dielectric type. Keep supply and return planes continuous beneath the device and isolate noisy switching nodes from the Ethernet and clock paths. Verify power-down-state current in the finished system because the intelligent shutdown modes can change total board consumption substantially.
Do not select a nominal 100-Mbps PHY solely from its data rate. The MII or RMII interface, clock source, PHY address, reset polarity, register behavior, magnetics, temperature grade, and exposed-pad geometry must also match the host design. When substituting an ordering option, compare the exact TI ordering table and verify initialization software against the selected MPN.
合规信息
The available product information identifies an industrial-temperature Ethernet PHY but does not state the requested environmental or material-compliance statuses. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals declarations for the exact ordering option from the manufacturer.
