ADM6993FX-AD-T-1

Overview

The ADM6993FX-AD-T-1 is a single-chip Ethernet solution integrating two 10/100 Mbps MDIX TX/FX transceivers, a three-port L2 switch controller, and a third MAC port configurable as GPSI, MII, RMII, or HDLC. It supports priority features including Port-Based, VLAN TAG, and IP TOS precedence checking. The device includes a built-in 6Kx64bit SRAM data buffer and supports up to 2k MAC Unicast addresses with a 4-way associative hashing table. It operates on a 2.5 V or 3.3 V power supply within the 128 PQFP package.

Feature Summary

• Integrates a three-port 10/100M Ethernet L2 switch controller with dual PHY transceivers.
• Supports converter mode with fault propagation and redundant link capabilities.
• Provides flexible MAC interface selection for Port 2 (MII/RMII/GPSI) and Port 3 (HDLC/MII/RMII/GPSI).
• Includes QoS features with two queues per port and support for 802.1p and TCP/IP ToS priority.

Applications

• Fiber-to-Ethernet media converters
• 2/3 port Ethernet switches
• VoIP gateways
• NAT routers

Procurement Notes

Verify component authenticity through authorized Infineon channels. Confirm datasheet revision Rev 1.11 compatibility during integration. Check environmental compliance documentation for the green package version. Ensure proper handling of the 128 PQFP packaging specifications during assembly.

Selection Notes

Select this component when a combined switching and conversion function is required in a single IC. Consider the specific MAC interface needs for Port 2 and Port 3 to determine if MII, RMII, GPSI, or HDLC modes are necessary. Verify power supply requirements align with the 2.5 V or 3.3 V operational ranges specified in the electrical characteristics.

Part Context

The ADM6993/X series serves as an integrated networking solution designed for compact applications requiring both switching and physical layer conversion. The FX variant specifically denotes the inclusion of Fiber (FX) transceiver capabilities alongside the standard Twisted Pair (TX) ports, enabling direct connection to fiber optic networks without external PHY components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Infineon Ethernet controllers based on pin compatibility and functional equivalence if replacement is required.
