Product details
Overview
ADM6996MX-AD-T-1 from Infineon Technologies is a six-port 10/100 Mbps L2 Ethernet switch controller with integrated MDIX TX/FX transceivers, hardware/software IGMP snooping, 16 VLAN support, and Layer 4 QoS for multimedia traffic prioritization. It operates in full/half-duplex mode and targets embedded broadband access equipment requiring deterministic packet handling and low-power operation (1.0 W).
For engineers reviewing the ADM6996MX-AD-T-1 datasheet, ADM6996MX-AD-T-1 pinout, ADM6996MX-AD-T-1 application, or ADM6996MX-AD-T-1 equivalent, key selection criteria include RMII/MII interface compatibility, 1784-byte maximum packet length support, 2K MAC address table with 4-layer hashing, IPv4/v6 DiffServ priority mapping, and 802.1x port-based authentication capability.
Technical Context
The ADM6996MX-AD-T-1 implements a fully integrated switch fabric with five 10/100 PHY ports and one RMII/MII CPU interface port. Its learning handler supports 2K MAC entries using 4-layer hash lookup, and its packet buffer management enables ingress/egress bandwidth control scalable from 64 Kbps to 100 Mbps in 64 Kbps steps.
It delivers L4 QoS via TCP/UDP destination port inspection, IP protocol ID filtering, and Ethernet type matching, enabling granular traffic classification. Security functions include 802.1x authentication, MAC address-based accept/reject filtering, and multicast broadcast storm protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar L2 Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM6996LC | Lacks IPv4/v6 DiffServ, RMII interface, and 1784-byte packet support; uses legacy 1K MAC table | Targeted at cost-sensitive ADSL2+ modems without advanced QoS or PPPoE offload needs | Select when design requires pin compatibility with legacy Samurai but omits L4 classification |
| RTL8367RB | 7-port 10/100 switch with built-in 5-port PHY; no RMII option; supports 802.1ad QinQ but lacks PPPoE identification | Optimized for SOHO switches with integrated PHYs; no dedicated DSL/Cable modem feature set | Choose for standalone managed switch designs where external PHY integration is unnecessary |
Compared with ADM6996LC, the ADM6996MX-AD-T-1 adds critical DSL/Cable-specific features including PPPoE packet identification and RMII host interface, while RTL8367RB trades protocol-specific intelligence for higher port density and integrated PHYs-making it unsuitable for carrier-grade CPE requiring precise traffic steering.

FAQ
What is the function of the RMII interface on ADM6996MX-AD-T-1?
The RMII interface provides a 2-bit-wide, 50 MHz synchronous data path between the ADM6996MX-AD-T-1 and an external host processor or baseband controller. It replaces the legacy 4-bit MII, reducing pin count and PCB routing complexity while maintaining full 100 Mbps throughput for CPU-switch communication in DSL and cable modems.
Does ADM6996MX-AD-T-1 support IEEE 802.1Q VLAN tagging?
Yes, ADM6996MX-AD-T-1 supports up to 16 IEEE 802.1Q VLANs with 12-bit VLAN ID learning and explicit tag insertion/removal per port. It enables strict priority queuing across VLANs using 802.1p CoS bits and permits VLAN membership configuration via MDC/MDIO or CPU interface registers.
How does the PPPoE Identification feature operate?
The PPPoE Identification feature inspects incoming Ethernet frames for PPPoE discovery (code 0x09) and session (code 0x00) headers. Only frames matching these codes are forwarded to the CPU interface; all others are switched normally. This eliminates software-based PPPoE detection overhead and ensures deterministic upstream authentication timing in DSL CPE.
Is external memory required for ADM6996MX-AD-T-1 operation?
No external memory is required for basic switching operation. The device integrates on-chip packet buffers, MAC address table (2K), VLAN table (16 entries), and configuration registers. An external EEPROM is optional for storing factory-default settings, LED configurations, and port mirroring rules, accessed via I²C-compatible interface.
