DP83620SQE/NOPB - 100Mbps Industrial Ethernet PHY | TI
MPN: DP83620SQE/NOPB ✓ Hoạt độngDP83620SQE/NOPB Tóm tắt
An Ethernet physical-layer transceiver is the circuit that converts digital Ethernet data into signals suitable for twisted-pair or optical communication links. The DP83620 belongs to the Ethernet PHY hierarchy and provides the physical signaling layer beneath the MAC and host controller. Its 100 Mbps capability supports legacy Fast Ethernet infrastructure while industrial temperature qualification makes it suitable for demanding embedded, communications, and industrial-control systems.
Key characteristics include support for both 10-Mbps and 100-Mbps data rates, fiber support through an FX interface, intelligent low-power states, and cable-length performance extending beyond IEEE specifications. The 25 MHz clock output allows a system designer to supply a shared reference clock with fewer external components. A 105 mA supply-current figure supports power-budget planning for 3.3 V systems.
The DP83620 uses a 48-pin WQFN package with an exposed thermal pad, enabling a compact PCB footprint and improved heat transfer when the pad is soldered to a ground plane. Its industrial operating range is -40°C to +85°C. Designers should preserve the manufacturer’s differential-pair geometry and provide adequate input and output decoupling to maintain signal integrity on copper links.
Typical uses include industrial Ethernet controllers, factory automation equipment, embedded network gateways, fiber-capable network interfaces, and copper-to-fiber media converters. The MII interface supports systems requiring a wider parallel bus, while RMII reduces pin count and board complexity in designs using a compatible Ethernet MAC.
For each new board, place the PHY close to the Ethernet connector, route each differential pair as a controlled-impedance pair, and keep the connector return path continuous. Confirm magnetics, termination, and RJ45 layout against the manufacturer’s reference design before releasing the PCB.

Ứng dụng tiêu biểu
DP83620SQE/NOPB phù hợp cho 6 Áp dụngs: Industrial Ethernet Gateway, Factory Automation Terminal, Copper-to-Fiber Media Converter, Embedded Network Appliance, Industrial Sensor Hub, Test and Measurement Instrument.
Industrial Ethernet Gateway
The DP83620SQE/NOPB fits an industrial Ethernet gateway that must connect an embedded controller to a 10/100-Mbps network. Its MII interface supports a wider parallel host bus, while RMII can reduce connection complexity when the selected Ethernet MAC supports it. The industrial-temperature range of -40°C to +85°C supports equipment deployed beyond room-temperature conditions. The 3.0 V to 3.6 V supply range, 105 mA typical current, and intelligent power-down states assist power budgeting, while the 25 MHz clock output can simplify shared clock distribution. The WQFN footprint should be placed close to the Ethernet transformer or connector so that controlled-impedance differential routing remains short.

Factory Automation Terminal
A factory automation terminal benefits from the DP83620SQE/NOPB because the device combines 10/100-Mbps Ethernet connectivity with an industrial temperature rating of -40°C to +85°C. It can support copper links and an optional fiber connection, allowing the same PHY design to serve short industrial copper runs or longer fiber-based campus links. MII and RMII options let the design accommodate either a conventional parallel Ethernet MAC or a reduced-pin serial MAC. Cable-length performance beyond IEEE specifications can add installation margin, although the final link budget must still be validated with the selected magnetics and physical cable.

Copper-to-Fiber Media Converter
The DP83620SQE/NOPB is well suited to a copper-to-fiber media converter because the industrial Ethernet PHY includes fiber support in addition to its single copper port. It operates from 3.0 V to 3.6 V and supports 10/100-Mbps data rates, allowing the converter to bridge conventional 100BASE-TX equipment to an optical link. MII provides a flexible parallel interface to converter logic, while RMII can lower host-side pin requirements. The 25 MHz clock output supports systems with a shared reference clock. Fiber implementation must follow the manufacturer’s FX pin assignments, isolation requirements, optical-driver interface, and exposed-pad grounding recommendations.

Embedded Network Appliance
An embedded network appliance can use the DP83620SQE/NOPB when it requires a dedicated 10/100-Mbps Ethernet front end without adopting a larger multi-port controller. The transceiver supports both MII and RMII, allowing host-interface selection based on the embedded processor’s Ethernet MAC and available I/O. Its 3.0 V to 3.6 V operating range aligns with common 3.3 V system rails, and the listed 105 mA typical current helps size the local regulator. The 48-pin WQFN package supports compact designs, but careful attention to differential routing, return-path continuity, isolation, and the exposed thermal pad remains necessary for reliable Ethernet performance.

Industrial Sensor Hub
The DP83620SQE/NOPB can provide network connectivity in an industrial sensor hub that bridges sensors or controllers over a 10/100-Mbps Ethernet backbone. The -40°C to +85°C industrial range is appropriate for equipment operating near machinery, while MII and RMII provide options for host integration. The single-port architecture keeps the physical interface focused and may simplify synchronization with a sensor-processing FPGA or microcontroller. The 25 MHz clock output can reduce clock-distribution requirements, and intelligent power-down states can help when the hub is idle. A sleep-mode strategy should nevertheless be tested because link startup time and application wake-up behavior affect the overall power budget.
Được đề xuất
Test and Measurement Instrument
The DP83620SQE/NOPB supports test and measurement instruments that need a reliable 10/100-Mbps Ethernet management or data port. RMII can simplify connections to a compact control processor, while MII offers additional host-bus flexibility. The device’s 3.0 V to 3.6 V supply range, typical 105 mA current, and industrial temperature operation are useful for a compact, rugged instrument architecture. JTAG support can assist board-level debug and configuration work. For laboratory equipment, keep the PHY-to-connector path short, provide a continuous return path beneath the differential pairs, and validate magnetics placement because connector and chassis-ground arrangements can materially affect emissions and immunity.

Ghi chú thiết kế
Place the DP83620SQE/NOPB close to the Ethernet transformer or connector, and route the TX and RX differential pairs as short, coupled, controlled-impedance traces. Maintain a continuous reference plane beneath each pair and avoid stubs, test pads, and unrelated high-speed nodes on the same layers. The exact separation and impedance values should follow the manufacturer’s layout guidance and the selected magnetics implementation.
Connect the exposed pad to the ground plane with a full-area solder connection and an appropriate thermal-via pattern. The 48-WQFN package has a compact thermal path, so a pad that is only partially soldered can increase junction temperature and reduce long-term reliability. Apply the manufacturer’s land pattern and reflow profile rather than substituting a generic QFN footprint.
Place the required input and output decoupling capacitors close to their associated DP83620SQE/NOPB pins, with the shortest practical ground paths. Confirm that the local 3.3 V rail can support the listed 105 mA typical current plus Ethernet magnetics and attached circuitry. Use the intelligent power-down modes only after verifying wake-up timing, link negotiation behavior, and the host’s ability to tolerate a delayed network restart.
Separate MII or RMII host signals from the differential Ethernet pairs where practical, and use the manufacturer’s clock-output and strap-configuration guidance when assigning boot behavior. The 25 MHz clock output offers design flexibility, but its routing and source selection must be checked carefully. Do not infer pin assignments from a generic Ethernet PHY because package and function arrangements can differ even when data-rate ratings match.
