Ethernet Connectivity on the TI AM572x Industrial Development Kit The TMDXIDK5728 / AM572x Industrial Development Kit (IDK) is an evaluation platform for industrial communication and control applications. Its Ethernet interfaces provide a useful reference for engineers working with industrial Ethernet, embedded networking and board-mounted RJ45 connectors. LINK-PP's existing application information identifies two magnetic RJ45 connector part numbers in connection with this board family: LPJ16183A28NL — a 10/100BASE-T RJ45 connector with integrated magnetics. LPJG16314A4NL — a 1000BASE-T RJ45 connector with integrated magnetics. The exact connector fitted to a board can depend on its hardware revision and bill of materials. Before ordering a replacement or using the design as a reference, check the marking on the installed connector and the documentation for the specific board. AM572x IDK Ethernet Port Configuration The AM572x IDK architecture includes Fast Ethernet interfaces connected to the PRU-ICSS subsystems and Gigabit Ethernet interfaces connected to the processor's Ethernet switch. According to Texas Instruments' hardware documentation, the default configuration provides: Ethernet interface Default available ports Connection path 100 Mbps Industrial Ethernet 2 PHY/MII to PRU-ICSS 1000 Mbps Gigabit Ethernet 2 PHY/RGMII to the integrated Ethernet switch An alternative hardware configuration can provide up to four 100 Mbps ports, subject to the board configuration described in the TI documentation. The number of physical connector positions and the number of Ethernet ports available concurrently are different considerations. Engineers should review the applicable board revision and TI documentation before changing resistor configurations or assigning ports. Reference: TI AM572x Industrial Development Kit Hardware Guide.

Use each complete drawing for tolerances, pin assignments, magnetic circuitry, PCB layout and assembly requirements. The two connectors must not be treated as interchangeable without a full electrical and mechanical review. LPJ16183A28NL for 10/100 Ethernet Applications The LPJ16183A28NL is a single-port, right-angle RJ45 connector with integrated magnetics for 10/100BASE-T Ethernet. It uses through-hole mounting, a tab-up latch and an EMI-shielded housing with spring fingers. According to LINK-PP drawing LP13012302 Rev A, the connector has nominal drawing dimensions of 21.25 x 15.95 x 13.45 mm and an operating temperature range of 0 to +70 degrees C. The electrical specification lists 350 uH minimum open-circuit inductance at 100 kHz, 0.1 V and 8 mA DC bias, as well as 1500 Vrms isolation from the PHY side to the line side. Electrical specifications are stated at 25 degrees C. The drawing identifies a green LED on the left and a yellow LED on the right. On the PCB-side schematic, the green LED circuit connects to pins 11 and 12, while the yellow LED circuit connects to pins 9 and 10. A 250-ohm series resistor is shown in each LED circuit. Before PCB release or connector replacement, review the complete drawing and board schematic. Confirm the magnetics connections, center taps, LED drive circuit, signal-pin holes, shield features, locating posts and mechanical clearances. The drawing provides a recommended PCB layout as a top view. LED Circuit Design Considerations The drawing shows left green LED pin 11 positive and pin 12 negative; right yellow LED pin 9 positive and pin 10 negative; a 250-ohm series resistor in each LED circuit; and LED forward voltage of 1.8–2.6 V at IF = 20 mA for both colors. The integrated resistor shown in the connector circuit should be considered when designing the external LED drive. Check the supply voltage, PHY output characteristics and current limits for the actual board; do not assume that the same external resistor network used with another RJ45 connector will produce the same LED current. LPJG16314A4NL uses a different LED arrangement: its green and yellow elements are shown anti-parallel on each side. Therefore, the two models' LED circuits and PCB pin assignments must be reviewed separately. LPJG16314A4NL for 1000BASE-T Gigabit Ethernet The LPJG16314A4NL is a single-port, tab-up RJ45 connector with integrated magnetics for 1000BASE-T applications. LINK-PP drawing LP11021127 Rev A specifies a 1:1 transformer turns ratio, 100-ohm impedance, 350 uH minimum open-circuit inductance at 100 kHz, 0.1 Vrms and 8 mA DC bias, 1500 Vrms minimum isolation voltage, 0 to +70 degrees C operating temperature and green/yellow LED indicators on both sides. The drawing shows nominal dimensions of 21.25 x 15.95 x 13.45 mm. Use the complete mechanical drawing for measurement references, tolerances and the recommended PCB layout. For product information and an engineering enquiry, visit the LPJG16314A4NL Gigabit RJ45 Magnetic Jack product page. PCB Design and Replacement Checklist 1. Confirm the board and connector position Identify the board revision, connector reference designator and installed part marking. Check whether the position belongs to a Fast Ethernet or Gigabit Ethernet circuit and whether that interface is available in the selected board configuration. 2. Compare the magnetics and PHY interface Use the current connector drawing and board schematic to compare PHY-side signal pairs and connector pinout, transformer turns ratio and center taps, termination and common-mode components, and isolation and other electrical requirements. A mechanical fit alone is not sufficient to establish compatibility. 3. Check the mechanical footprint Review connector orientation, board-edge placement, signal-pin holes, LED-pin holes, shield features and locating posts. Also check front-panel clearance and latch accessibility. 4. Verify the LED circuit Confirm LED colors, pin assignments and drive polarity for the selected part. On LPJG16314A4NL, the green and yellow LED elements on each side are shown in an anti-parallel arrangement; the system's PHY and driver circuit determine the indication behavior. 5. Validate the finished design Before production or field replacement, verify mechanical fit, Ethernet link operation and required system-level electrical performance on the target board. Frequently Asked Questions How many Ethernet ports can the AM572x IDK use at the same time? TI's hardware documentation states that the default configuration provides two 100 Mbps Industrial Ethernet ports and two Gigabit Ethernet ports. Alternative hardware configuration options change the available interfaces. Consult the documentation for the specific board revision before making changes. What is the difference between LPJ16183A28NL and LPJG16314A4NL? LPJ16183A28NL is a 10/100BASE-T magnetic RJ45 connector. LPJG16314A4NL is specified for 1000BASE-T applications. Their magnetics circuits, pinouts and LED configurations must be checked individually. Can the two connectors be used as drop-in replacements for each other? Do not assume that they are interchangeable. Compare the complete electrical schematic, PCB footprint, LED circuit and mechanical drawing with the target board before approving a replacement. Do these connectors support PoE? The supplied LPJG16314A4NL drawing does not specify a PoE rating, and published product information identifies LPJ16183A28NL as a non-PoE Ethernet part. For a PoE design, select a connector with documented support for the required power standard and operating conditions. Where can I obtain drawings and engineering support?

A board name or matching Ethernet speed alone does not establish that every production version uses the same part. For complete specifications and product information, visit the LPJG16314A4NL 1000BASE-T RJ45 Magnetic Jack product page. LPJG16314A4NL Specifications at a Glance Parameter Specification Manufacturer LINK-PP Part number LPJG16314A4NL Product type RJ45 connector with integrated magnetics Ethernet application 1000BASE-T Gigabit Ethernet Port configuration 1 x 1 single port Mounting and orientation Through-hole, right angle Latch orientation Tab up LEDs Green/yellow on both left and right sides Drawing dimensions 21.25 mm length x 15.95 mm width x 13.45 mm height Impedance 100 ohms Transformer turns ratio 1:1 Open-circuit inductance 350 uH minimum at 100 kHz, 0.1 Vrms and 8 mA DC bias Isolation voltage 1500 Vrms minimum Operating temperature 0 to +70 ℃ Wave solder condition 265 ℃ maximum tip temperature, 5 seconds maximum Drawing reference: LINK-PP LP11021127, Rev A. The drawing states electrical specifications at 25 ℃. Dimensions are shown for quick reference; use the complete drawing, including its measurement references and tolerances, for PCB and enclosure design. Why Use an RJ45 Connector with Integrated Magnetics? A Gigabit Ethernet interface requires the connector and magnetic network to be coordinated with the Ethernet PHY and PCB layout. The LPJG16314A4NL integrates the magnetic components into the RJ45 connector package, providing a defined connector and magnetics configuration for a board-mounted Ethernet interface. For an engineer, the drawing provides more than an exterior outline. It shows the relationship between the PCB-side connections, the RJ45 contacts, transformer windings, common-mode components and termination network. These details should be reviewed together with the selected PHY reference design rather than treated as interchangeable across all magnetic jacks. The product drawing specifies a 1:1 turns ratio, 100-ohm impedance and 1500 Vrms minimum isolation voltage. System-level Ethernet and isolation performance still depend on the complete circuit, PCB layout and validation of the finished equipment. MinnowBoard MAX Application: Check the Board Revision First MinnowBoard MAX documentation and design files are useful starting points when examining the board's Ethernet interface. LINK-PP identifies LPJG16314A4NL as a connector associated with the MinnowBoard MAX application; however, connector sourcing and board designs can change between revisions. Before ordering a replacement or reusing the design: Identify the exact MinnowBoard MAX hardware revision. Inspect the marking on the connector fitted to the board. Compare the board's schematic and bill of materials with the connector drawing. Check the PCB footprint, LED circuit and mechanical clearance. Validate the replacement on the target board. The MinnowBoard official hardware design files can help engineers locate revision-specific design information. The final selection should be based on the documentation for the actual board under review. RJ45 Datasheet - Mechanical Dimensions and PCB Footprint The LPJG16314A4NL drawing shows a right-angle connector with nominal dimensions of 21.25 mm length, 15.95 mm width and 13.45 mm height. It uses a tab-up latch configuration and through-hole PCB mounting. The suggested PCB layout is presented in the drawing as a top view. It includes separate hole patterns for the PCB-side connections, LED pins, shield features and locating posts. Before creating or approving a footprint, compare the hole diameters and center-to-center positions with the latest drawing and the PCB manufacturer's capabilities. Pay particular attention to the connector position relative to the PCB edge and front-panel opening; signal-pin and LED-pin hole locations; shield and locating-post holes; housing and latch clearance; and the drawing's dimensional tolerances and measurement references. A connector with the same front opening may have a different footprint or shield layout. Confirm the actual mechanical drawing before treating another part as a replacement. Green/Yellow LED Configuration and Pinout The LPJG16314A4NL has a green/yellow LED on the left and another green/yellow LED on the right. According to the schematic, the left LED uses PCB pins 13 and 14, and the right LED uses PCB pins 11 and 12. The green and yellow LED elements on each side are shown in an anti-parallel configuration. The drawing lists a forward voltage of 1.8–2.6 V at 20 mA for both green and yellow emitters. Because the two colors on each side are connected in opposite directions, the emitted color depends on the applied polarity and the board's drive circuit. Review the complete schematic and LED driver design before assigning a fixed anode or cathode label to a two-pin LED pair. LED behavior, such as link or activity indication, is determined by the system's PHY and circuit configuration. It should not be assumed solely from the connector's LED colors. Electrical Characteristics for Design Review The drawing lists electrical characteristics at 25 degrees C: 100-ohm impedance; 1:1 turns ratio; open-circuit inductance of 350 uH minimum at 100 kHz, 0.1 Vrms and 8 mA DC bias; insertion loss of -1.1 dB maximum over 0.5–100 MHz, as stated in the drawing; and isolation voltage of 1500 Vrms minimum. The specified operating temperature is 0 to +70 degrees C. The drawing also provides return-loss, crosstalk and common-mode rejection requirements over specified frequency ranges. Engineers should consult the full electrical specification and test conditions when comparing the connector with a PHY reference design or an alternative part. The drawing does not specify an isolation test duration or a PoE rating. Confirm those requirements separately if they are important to the end product. Selecting a Gigabit RJ45 Connector for an Embedded Board For an embedded board or networking product, evaluate the connector as part of the complete Ethernet interface: Ethernet speed: Confirm that the connector and magnetics support the required 1000BASE-T interface and PHY configuration. Electrical circuit: Compare the transformer ratio, center-tap arrangement and PCB-side pinout with the PHY reference circuit. Mechanical configuration: Check the tab-up orientation, board-edge position, hole pattern and enclosure opening. LED design: Confirm the green/yellow LED arrangement, anti-parallel pinout and drive circuit. Operating conditions: Verify that the specified 0 to +70 degrees C range meets the equipment environment. Manufacturing process: Review the wave solder limit and complete assembly process with the manufacturer. PoE requirement: Do not assume PoE compatibility when it is not specified in the drawing. A footprint or speed match is a starting point. Electrical, thermal and mechanical validation are still needed before approving a part for production. Applications of Gigabit RJ45 Connector  Depending on system requirements and validation, a 1000BASE-T RJ45 connector with integrated magnetics may be considered for embedded development and evaluation boards, Gigabit Ethernet interfaces on networked control equipment, LAN-on-motherboard designs, Ethernet hubs and switches, and other board-mounted Ethernet products operating within the connector's specified conditions. The equipment designer is responsible for confirming suitability for the intended circuit, environment and manufacturing process. Frequently Asked Questions 1.
