ADM6996LX-AA-R-1

Overview

The ADM6996LX-AA-R-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. 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 a parallel interface for management. Key specifications include support for up to 2048 MAC addresses, four priority queues, and 802.1Q VLAN capabilities.

Feature Summary

• Integrates five 10/100 Mbps auto-detect switch ports with TX/FX interfaces and one 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, supporting store-and-forward architecture at non-blocking wire speed.
• Provides 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 switches combined with router functionality via MII CPU interface

Procurement Notes

Verify component authenticity and datasheet version compatibility before integration. Confirm that the specific ordering suffix matches the required package and configuration parameters. Ensure all electrical and environmental specifications align with the target system design requirements.

Selection Notes

Evaluate the need for integrated PHY and memory against discrete solutions. Consider the 128-pin package size and thermal characteristics for the enclosure design. Verify that the supported voltage range and operating temperature meet the application's environmental constraints.

Part Context

This component belongs to the ADM6996 series of Ethernet switch controllers. It represents a highly integrated solution designed to reduce bill-of-materials costs by combining switching logic, physical layer transceivers, and memory on a single die.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ADM6996A1T3, ADM6996A2T1, and ADM6996FCX-AC-T-1 from Infineon Technologies.
