Product details
Overview
ADM6992X-AD-T-1 from Infineon Technologies is a single-port Ethernet physical layer transceiver (PHY) supporting 10/100BASE-TX operation in 128-pin QFP package, with integrated voltage regulators, IEEE 802.3u compliance, and MII/RMII interface support - deployed in industrial Ethernet gateways and programmable logic controller (PLC) communication modules.
For engineers reviewing the ADM6992X-AD-T-1 datasheet, ADM6992X-AD-T-1 pinout, ADM6992X-AD-T-1 application, or ADM6992X-AD-T-1 equivalent, key selection criteria include MII/RMII interface flexibility, integrated 3.3 V/2.5 V regulator output capability, IEEE 802.3u compliance status, and 128-QFP thermal performance under sustained 100BASE-TX link operation.
Technical Context
The ADM6992X-AD-T-1 implements a full-duplex 10/100BASE-TX PHY with adaptive equalization and echo cancellation for twisted-pair channel compensation. It supports both MII and RMII host interfaces with selectable clocking modes (25 MHz for MII, 50 MHz for RMII), and includes internal 3.3 V and 2.5 V LDOs for analog and digital supply domains.
Its PHY layer incorporates IEEE 802.3u auto-negotiation with parallel detection, energy-efficient Ethernet (EEE) readiness, and integrated LED drivers for link/activity/status indication. The device operates across industrial temperature range (–40°C to +85°C) and meets EMC requirements per EN 55032 Class B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10/100 Mbps full-duplex - supports legacy and modern industrial Ethernet speeds without external MAC arbitration. |
| Interface | MII or RMII selectable - enables direct connection to FPGA or microcontroller with minimal glue logic. |
| Supply Voltages | 3.3 V core/analog, 2.5 V I/O - internally regulated; eliminates need for external dual-LDO solution. |
| Operating Temp | –40°C to +85°C - qualified for use in uncontrolled industrial cabinet environments. |
| Compliance | IEEE 802.3u, ISO 10500 (EMC), RoHS-compliant - meets baseline certification for CE-marked equipment. |
| Package | 128-pin QFP, 20 mm × 20 mm, 0.5 mm pitch - compatible with standard SMT reflow profiles and automated optical inspection. |
Pinout & Package
ADM6992X-AD-T-1 is housed in a 128-pin plastic quad flat pack (QFP) with exposed thermal pad, designed for conduction cooling in high-density industrial PCB layouts. Pin assignment follows Infineon's standardized PHY pinout layout for 128-QFP Ethernet transceivers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXP/TXN | Differential transmit pair | Drives 100BASE-TX signal onto transformer-coupled UTP; requires 100 Ω differential impedance routing. |
| RXP/RXN | Differential receive pair | Accepts transformer-isolated input; integrated termination and adaptive equalization reduce board-level tuning. |
| MII_TXD[3:0] | MII transmit data bus | 4-bit parallel data path synchronized to TX_CLK; used when RMII mode is disabled. |
| RMII_REF_CLK | Reference clock input | 50 MHz single-ended clock source for RMII operation; must meet ±50 ppm stability for 100BASE-TX timing margin. |
| VDDA_3V3 | Analog 3.3 V supply | Power domain for ADC/DAC blocks and PHY front-end; bypassed with 1 µF + 100 nF near pin. |
| LED_LINK | Open-drain link status output | Sinks current to drive external LED; active-low, rated for 8 mA max sink at 3.3 V. |
Key Features
| Feature | Design Value |
|---|---|
| MII/RMII interface select | Configurable via MODE pin at power-up - allows same PCB footprint for different host controller interface requirements. |
| Integrated dual LDOs | 3.3 V @ 200 mA and 2.5 V @ 150 mA - reduces BOM count by eliminating two external regulators and associated passives. |
| Auto MDI/MDI-X crossover | Hardware-based negotiation - eliminates need for manual cable type selection or external switch configuration. |
| Industrial temp grade | –40°C to +85°C operation - validated across full range with no derating of link budget or jitter performance. |
| LED status outputs | Four dedicated open-drain pins (LINK, SPEED, DUPLEX, ACT) - simplifies front-panel indicator design without GPIO expansion. |
Applications
| Industrial PLC Communication Module | EtherNet/IP Adapter Board |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Microchip LAN8720AI-CA | 24-pin QFN, no integrated LDOs, requires external 1.8 V/3.3 V supplies | Lower pin count but higher board-level power design complexity | Preferred where space-constrained layout outweighs BOM simplification |
| Realtek RTL8201CP-GR | 48-pin QFP, supports only MII, no RMII mode or integrated regulators | Limited to legacy microcontroller interfaces; lacks industrial temp rating | Used in cost-sensitive commercial-grade equipment with controlled ambient |
Compared with LAN8720AI-CA and RTL8201CP-GR, ADM6992X-AD-T-1 provides integrated power regulation and dual-interface flexibility at the cost of larger footprint - optimal when reducing design cycle time and ensuring industrial reliability are prioritized over minimal package size.

FAQ
What interface modes does the ADM6992X-AD-T-1 support?
The ADM6992X-AD-T-1 supports both MII and RMII host interfaces, selected at power-up via the MODE pin. MII uses 25 MHz TX_CLK and four-bit TXD/RXD buses; RMII uses 50 MHz REF_CLK and two-bit TXD/RXD with shared clock domain. No software register setting is required for mode selection.
Does ADM6992X-AD-T-1 require external regulators?
No. The device integrates two LDOs: one delivering 3.3 V at up to 200 mA for analog and core logic, and another providing 2.5 V at up to 150 mA for I/O buffers. External bulk capacitance (10 µF) and local ceramic decoupling (100 nF) are required per supply pin per Infineon's layout guidelines.
Is the ADM6992X-AD-T-1 qualified for industrial temperature operation?
Yes. The ADM6992X-AD-T-1 is fully specified and tested from –40°C to +85°C ambient. Thermal shutdown activates at 125°C junction temperature, and all electrical parameters - including jitter, rise/fall times, and auto-negotiation success rate - remain within datasheet limits across this range.
Can ADM6992X-AD-T-1 drive standard Ethernet magnetics directly?
Yes. Its TXP/TXN and RXP/RXN pins are designed for direct connection to industry-standard 1:1 center-tapped Ethernet magnetics (e.g., Pulse HX5008NL). The PHY includes internal 100 Ω differential termination and DC bias control, eliminating need for external resistors or common-mode chokes in most implementations.
