ADM6993X-AD-T-1

Overview

The ADM6993X-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 converter mode capabilities. It features a built-in 6Kx64bit SRAM data buffer and supports up to 2k MAC unicast addresses with a 4-way associative hashing table. The device operates on a 2.5V or 3.3V power supply and utilizes a 128-pin PQFP package.

Feature Summary

• Integrates a 3-port 10/100M switch with dual PHYs and a third MAC port configurable as GPSI, MII, RMII, or HDLC.
• Supports priority-based QoS including Port-Base, VLAN TAG, and IP TOS precedence checking.
• Provides TX FX Converter modes with fault propagation and redundant link capabilities.
• Includes broadcast storm filtering and store-and-forward architecture for efficient packet handling.

Applications

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

Procurement Notes

Verify component authenticity through authorized Infineon channels due to discontinued status. Confirm the specific AD suffix indicates the green package variant. Request original datasheets and test reports to ensure compliance with RoHS standards before integration into production systems.

Selection Notes

Select this component when designing systems requiring integrated switching and conversion functions in a single IC. Ensure the host microcontroller supports the required Serial Management Interface (SMI) for configuration. Verify that the application environment accommodates the specified operating temperature range and voltage requirements.

Part Context
