Product details
Overview
ADM6992KX-AB-T-1 from Infineon Technologies is a managed Ethernet OAM (Operations, Administration, and Maintenance) processor IC designed for carrier-grade access equipment. It supports IEEE 802.3ah, 802.1ag, and ITU-T Y.1731 standards, integrates dual 10/100/1000BASE-T PHYs, delivers full OAM PDU processing, and operates in industrial temperature range (–40°C to +85°C) for DSLAM and fiber access node applications.
For engineers reviewing the ADM6992KX-AB-T-1 datasheet, ADM6992KX-AB-T-1 pinout, ADM6992KX-AB-T-1 application, or ADM6992KX-AB-T-1 equivalent, key selection criteria include OAM protocol stack depth, integrated PHY compliance level, MAC-to-PHY interface type (RGMII), and support for hardware-accelerated continuity check (CC), loopback (LB), and link trace (LT) functions.
Technical Context
The ADM6992KX-AB-T-1 implements a dedicated OAM processing engine with hardware offload for Ethernet CFM (Connectivity Fault Management) and EFM (Ethernet in the First Mile). It features two independent 10/100/1000BASE-T PHYs compliant with IEEE 802.3ab and 802.3u, and supports RGMII v2.0 interface to external MAC controllers at 1.8 V I/O voltage.
It includes embedded SRAM for OAM PDU buffering, supports up to 4096 maintenance endpoints (MEPs), and provides configurable aging timers, statistics counters per MEP, and hardware-based frame loss measurement per maintenance association (MA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OAM Standards | IEEE 802.3ah (EFM), 802.1ag (CFM), ITU-T Y.1731 - enables end-to-end fault detection and service assurance in metro Ethernet networks |
| PHY Integration | Dual 10/100/1000BASE-T PHYs - eliminates need for external PHYs and reduces BOM count in access concentrators |
| MAC Interface | RGMII v2.0, 1.8 V - ensures interoperability with common network processors and SoCs without level-shifting |
| Maintenance Endpoints | Up to 4096 MEPs - supports large-scale multi-tenant DSLAM deployments with per-subscriber OAM visibility |
| Temperature Range | –40°C to +85°C - qualified for uncontrolled cabinet environments in outdoor broadband access nodes |
| Package | 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) - compatible with standard SMT reflow profiles and automated optical inspection |
Pinout & Package
ADM6992KX-AB-T-1 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad for enhanced heat dissipation in fanless access equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PHY0_RXD[3:0] | Receive data from PHY0 | 4-bit RGMII receive data bus for first Gigabit Ethernet port |
| PHY1_TXC | Transmit clock output to PHY1 | 125 MHz RGMII transmit clock sourced from internal PLL for second port |
| MEP_INT | OAM event interrupt output | Active-low signal indicating MEP-level fault (e.g., CC timeout, LB failure) |
| REFCLK_IN | Reference clock input | 25 MHz crystal or oscillator input for PHY and OAM timing subsystem |
| VDDIO_1P8 | I/O power supply | 1.8 V supply for RGMII and control I/Os; requires local 10 µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Hardware OAM PDU parsing | Full-layer-2 OAM frame decode/encode in silicon - reduces host CPU load by >95% vs. software-only implementations |
| Per-MEP statistics | Real-time counters for frames sent/received, CCMs lost, LT responses - enables SLA monitoring per subscriber VLAN |
| Configurable aging timer | Programmable MEP timeout from 100 ms to 30 s - adapts to varying network latency and topology stability requirements |
| Embedded SRAM buffer | 16 kB on-chip SRAM for OAM PDU queueing - avoids external memory and associated timing constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet OAM processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E6393X | Integrated 8-port switch + OAM engine; no dual PHYs - requires external PHYs for copper interfaces | Targeted at compact switch-based OAM nodes, not standalone OAM processors | Select when switching functionality is needed alongside OAM, not for pure OAM acceleration |
| Microchip LAN9354 | Single 10/100/1000BASE-T PHY; supports only 802.3ah EFM, lacks 802.1ag CFM and Y.1731 | Suitable for basic EFM in residential gateways, not carrier-grade CFM deployments | Select for cost-sensitive EFM-only use cases where CFM/MA-level diagnostics are unnecessary |
Compared with Marvell 88E6393X and Microchip LAN9354, ADM6992KX-AB-T-1 uniquely combines dual full-spec PHYs with hardware-accelerated CFM/Y.1731 - making it the only option for high-density, carrier-class OAM termination without external PHYs or protocol stack compromises.

FAQ
Does ADM6992KX-AB-T-1 support IEEE 802.1Qbb (Priority-based Flow Control)?
No. The ADM6992KX-AB-T-1 implements only IEEE 802.3ah, 802.1ag, and ITU-T Y.1731 OAM protocols. It does not include PFC logic or pause frame generation capability. Flow control must be handled externally by the connected MAC or switch controller.
What is the maximum number of Maintenance Associations (MAs) supported?
The ADM6992KX-AB-T-1 supports up to 256 concurrent Maintenance Associations. Each MA can contain up to 4096 MEPs, and MA configuration is stored in internal register space with hardware-assisted lookup.
Is an external crystal required for operation?
Yes. A 25 MHz fundamental-mode crystal must be connected to REFCLK_IN and REFCLK_OUT pins. The internal PLL uses this reference to generate all PHY and OAM timing signals; no internal oscillator is provided.
Can the RGMII interface operate at 3.3 V I/O voltage?
No. The RGMII interface is strictly 1.8 V tolerant. Driving RGMII signals at 3.3 V will damage the I/O cells. Level-shifting circuitry or a 1.8 V-compatible MAC controller is mandatory for interfacing.
