Product details
Overview
ADM6996FCX-AD-R-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, Layer 4 QoS, and 802.1x security-designed for ADSL routers and home gateways requiring deterministic traffic prioritization and multicast control.
For engineers reviewing the ADM6996FCX-AD-R-1 datasheet, ADM6996FCX-AD-R-1 pinout, ADM6996FCX-AD-R-1 application, or ADM6996FCX-AD-R-1 equivalent, key selection criteria include IEEE 802.1p/q compliance, 128-pin LQFP package compatibility, RMII/MII interface flexibility, 1784-byte maximum packet length, and hardware-accelerated IGMP/STP implementation.
Technical Context
The ADM6996FCX-AD-R-1 implements a full L2 switching fabric with 2K MAC address table capacity, 4-layer hashing, and hardware-based learning. It supports both MII and RMII host interfaces, enabling direct connection to ARM or MIPS CPUs without external PHY bridging.
Its ingress/egress bandwidth control scales from 64 Kbps to 100 Mbps per port in 64 Kbps increments, and it enforces TCP/UDP destination port–based filtering, IP protocol ID matching, and Ethernet type–based ACLs-critical for residential gateway traffic shaping and DoS mitigation.
Key Specifications

| Switching Capacity | 1.2 Gbps non-blocking throughput supporting concurrent 10/100 traffic on all ports |
| VLAN Support | 16 IEEE 802.1q VLANs with 12-bit VLAN ID learning and tagging |
| Max Packet Length | 1784 bytes-enables jumbo frame handling for VoIP and IPTV streaming payloads |
| Power Dissipation | 1.0 W typical-meets thermal constraints for fanless SOHO router enclosures |
| Interface Options | MII and RMII CPU interfaces-reduces PCB layer count and simplifies layout vs. GMII |
| Security Features | 802.1x authentication, MAC address filtering (accept/reject), and PPPoE packet identification |
Pinout & Package
ADM6996FCX-AD-R-1 is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad for enhanced heat dissipation in compact router designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MDC/MDIO | Management Data Clock / Input-Output | IEEE 802.3-compliant serial interface for PHY register configuration and status polling |
| RMII_CLK | Reference Clock Input | 50 MHz clock input for RMII mode; enables reduced pin count vs. MII |
| TXD[3:0]/RXD[3:0] | RMII Transmit/Receive Data | 4-bit parallel data path for 10/100 Mbps RMII communication with host CPU |
| LED[5:0] | Link/Activity Status Outputs | Dedicated open-drain outputs per port for dual-color LED indication (link + activity) |
| XTAL_IN/XTAL_OUT | Clock Oscillator Interface | Supports 25 MHz crystal for internal PLL generation of all required system clocks |
Key Features
| Feature | Design Value |
|---|---|
| Hardware IGMP Snooping | Reduces multicast flooding by dynamically updating forwarding tables based on IGMP reports-essential for VOD and IPTV deployments |
| Layer 4 QoS Engine | Classifies and prioritizes traffic using TCP/UDP port numbers, IP protocol ID, and Ethernet type-enables differentiated service for VoIP, gaming, and web traffic |
| Port Mirroring | Enables real-time traffic analysis and intrusion detection by duplicating selected port traffic to a monitoring port without software overhead |
| Spanning Tree Protocol (STP) | Prevents network loops in redundant topologies via IEEE 802.1D-compliant BPDU processing in hardware |
| PPPoE Identification | Filters and forwards only valid PPPoE discovery and session packets-eliminates CPU load from parsing non-PPPoE frames in DSL environments |
Applications
| ADSL Routers | Home Gateways |
|---|---|
Use Scenario: Residential broadband aggregation with DSL line termination, NAT, firewall, and Wi-Fi backhaul. IC Role / Device Role / Timing Role: Central L2 switch controller managing WAN/LAN traffic separation, VLAN tagging, and QoS policy enforcement. Use Value: Hardware-accelerated IGMP snooping prevents multicast storm in IPTV delivery; 1784-byte packet support accommodates encapsulated DSL framing. | Use Scenario: Multi-service convergence platform integrating VoIP, USB storage, and wired/wireless LAN. IC Role / Device Role / Timing Role: Traffic arbitration engine enforcing priority queues for voice (802.1p), video (DSCP), and best-effort data streams. Use Value: L4 QoS with TCP/UDP port classification ensures low-latency VoIP call setup and media transport across shared uplink bandwidth. |
| Wireless Routers | Cable Modems |
Use Scenario: Dual-band 802.11n/ac access point with simultaneous 2.4 GHz and 5 GHz SSIDs and wired uplink. IC Role / Device Role / Timing Role: Backplane switch connecting Wi-Fi SoC, WAN PHY, and LAN ports with per-port bandwidth limiting. Use Value: Ingress/egress rate control (64 Kbps–100 Mbps) prevents Wi-Fi congestion from overwhelming upstream cable link; RMII interface saves PCB space. | Use Scenario: DOCSIS 3.0 compliant cable modem with embedded routing and MoCA LAN extension. IC Role / Device Role / Timing Role: Secure switching node applying 802.1x authentication and MAC address filtering before traffic reaches cable interface. Use Value: Hardware 802.1x supplicant offloads CPU during subscriber provisioning; "Accept/Reject" MAC list blocks unauthorized CPE devices at L2. |
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 |
|---|---|---|---|
| ADM6996LCX-AD-R-1 | Lacks RMII interface; supports MII only; no TCP/UDP port–based filtering | Targeted at legacy designs with fixed MII CPU interface and simpler QoS needs | Select when RMII is unnecessary and cost sensitivity outweighs advanced L4 classification |
| RTL8306SD-GR | 6-port 10/100 switch with 2K MAC table but no hardware IGMP snooping or PPPoE identification | Used in basic SOHO switches where multicast optimization and DSL-specific features are not required | Choose for cost-driven, non-DSL applications lacking strict multicast or PPPoE requirements |
Compared with ADM6996LCX-AD-R-1 and RTL8306SD-GR, the ADM6996FCX-AD-R-1 uniquely delivers RMII support, hardware PPPoE packet recognition, and TCP/UDP port–driven QoS-making it optimal for next-generation DSL and hybrid fiber-coax residential gateways.

FAQ
Does ADM6996FCX-AD-R-1 support Gigabit Ethernet?
No. ADM6996FCX-AD-R-1 is strictly a 10/100 Mbps L2 switch controller. It does not implement 1000BASE-T PHYs or GMII interfaces. Its maximum per-port speed is 100 Mbps full-duplex, and its switching fabric is rated for 1.2 Gbps aggregate throughput across six 100 Mbps ports.
Can ADM6996FCX-AD-R-1 operate without an external EEPROM?
Yes. Default configuration is stored in internal ROM; EEPROM is optional for custom settings such as MAC address, VLAN mapping, and port mirroring rules. The device boots and functions with factory defaults if EEPROM is unpopulated or unreadable.
What is the function of the "Special Tag" feature?
The Special Tag feature inserts or interprets proprietary 4-byte tags in Ethernet frames for vendor-specific control signaling-used in Infineon reference designs for inter-chip communication between Samurai and companion PA/WARP processors, enabling synchronized QoS and power management decisions.
Is ADM6996FCX-AD-R-1 qualified for industrial temperature range?
No. ADM6996FCX-AD-R-1 is specified for commercial temperature range (0 °C to +70 °C). It is not rated for extended industrial (-40 °C to +85 °C) operation. Thermal design must ensure junction temperature remains within this limit under 1.0 W typical power dissipation.
