ADM6996LX-AA-T-1

Overview

The ADM6996LX-AA-T-1 is a single-chip Ethernet switch controller manufactured by Infineon Technologies. It integrates five 10/100 Mbps twisted pair ports and one MII interface port, supporting full/half duplex operation across all interfaces. The device operates on a 2.8V to 3.465V power supply and functions within a temperature range of 0°C to 115°C. Packaged in a 128-pin BFQFP (PG-BFQFP-128), it utilizes parallel interfaces for management and control.

Feature Summary

• Integrates five 10/100 Mbps auto-detect switch ports with TX/FX interfaces alongside one dedicated MII/GPSI port.
• Supports Quality of Service through four queues and priority features based on Port-Based, 802.1p VLAN, and IP TOS fields.
• Includes built-in SRAM for packet buffering and address learning, capable of recognizing up to 2048 MAC addresses.
• Provides hardware flow control mechanisms including 802.3x pause packets for full duplex and back pressure for half duplex modes.

Applications

• Standalone bridge applications for the SOHO market
• Five-port network switches
• Router implementations utilizing the MII CPU interface

Procurement Notes

Verify component authenticity against official Infineon documentation before integration. Confirm that the specific ordering suffix matches the required package type and voltage specifications. Ensure compatibility with existing system power rails and interface timing requirements during the design phase.

Selection Notes

Select this controller for designs requiring integrated PHY and switching logic without external memory dependencies. Evaluate the 128-pin BFQFP footprint constraints and thermal dissipation capabilities relative to the operating environment. Verify support for required VLAN and QoS configurations against application needs.

Part Context

This component belongs to the ADM6996 series of Ethernet switch controllers. It represents a highly integrated solution combining MAC, PHY, and switching fabric functionalities into a single silicon die, designed to reduce bill-of-materials costs for compact networking equipment.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ADM6996A1T3, ADM6996A2T1, and ADM6996FCX-AC-T-1. Verify pinout and register compatibility when transitioning between these variants.
