Product details
Overview
ADM6996LCX-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 ADM6996LCX-AD-R-1 datasheet, ADM6996LCX-AD-R-1 pinout, ADM6996LCX-AD-R-1 application, or ADM6996LCX-AD-R-1 equivalent, key selection criteria include 128-pin LQFP package compatibility, RMII/MII interface support, 1784-byte maximum packet length, and hardware-accelerated IGMP/STP functions in legacy migration designs.
Technical Context
The ADM6996LCX-AD-R-1 implements a full-Layer 2 switching architecture with five 10/100 PHY ports plus one MAC-only port (Port 5), supporting both MII and RMII host interfaces. Its learning handler maintains a 2K-entry MAC address table using 4-layer hashing and supports 12-bit VLAN ID learning.
It delivers deterministic QoS via L4-based classification (TCP/UDP destination port, IP protocol ID, Ethernet type), ingress/egress bandwidth control scalable from 64 Kbps to 100 Mbps in 64 Kbps steps, and multicast broadcast storm protection with hardware IGMP snooping and multicast table management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Ports | 6-port L2 switch: 5× 10/100 Mbps MDIX TX/FX PHY + 1× MAC-only port (Port 5) |
| Max Packet Length | 1784 bytes - enables jumbo frame handling for VoIP and video streaming payloads |
| VLAN Support | 16 VLANs with 12-bit VLAN ID learning - allows segmented network isolation in multi-tenant gateways |
| MAC Table Size | 2,048 entries with 4-layer hashing - ensures stable address resolution under high-concurrency client loads |
| Power Dissipation | 1.0 W typical - enables fanless operation in compact DSL/home gateway enclosures |
| Interface Options | MII and RMII host interfaces - provides flexibility for ARM9/ARM11 or MIPS-based SoC integration |
| Security Features | 802.1x authentication, MAC address filtering ("Accept/Reject"), PPPoE packet identification - enforces subscriber-level access control in ISP CPE |
Pinout & Package
ADM6996LCX-AD-R-1 is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.4 mm pitch) with exposed thermal pad. Pin assignments follow Infineon's Samurai standard layout for pin-compatible migration from ADM6995/6L/F series.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MDIO / MDC | Management Data I/O / Clock | IEEE 802.3-compliant serial interface for PHY register configuration and status readback |
| RMII_CLK / RXD[1:0] / TXD[1:0] | RMII Interface Signals | Enables 2-pin clock + 4-pin data connection to host CPU, reducing PCB routing complexity vs. full MII |
| LED[0:5] | Link/Activity Status Outputs | Dedicated open-drain outputs per port for direct LED drive without external logic |
| XTAL_IN / XTAL_OUT | Crystal Oscillator Interface | Supports 25 MHz fundamental-mode crystal for precise 10/100 timing compliance |
| EEPROM_SCL / SDA | I²C Configuration Interface | Loads startup configuration (VLAN, QoS, security settings) from external EEPROM at power-on |
Key Features
| Feature | Design Value |
|---|---|
| Hardware IGMP Snooping | Reduces multicast flooding by dynamically updating forwarding decisions based on IGMP reports - critical for VOD delivery efficiency |
| L4 QoS Classification | Classifies traffic by TCP/UDP destination port, IP protocol ID, and Ethernet type - enables granular bandwidth allocation for VoIP, gaming, and web traffic |
| Port Mirroring | Allows real-time monitoring of any port's ingress/egress traffic on a dedicated analysis port - simplifies network diagnostics in embedded CPE |
| PPPoE Identification | Filters and forwards only valid PPPoE discovery and session packets - prevents DoS via malformed PPPoE frames in DSLAM-facing ports |
| Spanning Tree Protocol (STP) | Prevents Layer 2 loops in redundant topologies - required for reliable meshed home networks with multiple bridges |
Applications
| ADSL Routers | Home Gateways |
|---|---|
Use Scenario: Aggregating DSL line input with multiple wired LAN clients and Wi-Fi AP backhaul. IC Role / Device Role / Timing Role: Central L2 switching fabric managing VLAN-tagged subscriber traffic, PPPoE termination handoff, and QoS-marked VoIP streams. Use Value: Hardware IGMP snooping eliminates multicast flooding across DSL lines, preserving upstream bandwidth for concurrent IPTV sessions. | Use Scenario: Multi-service residential gateway supporting telephony (VoIP), internet, and IPTV over shared Ethernet infrastructure. IC Role / Device Role / Timing Role: Traffic classifier and scheduler enforcing priority queues for SIP signaling, RTP media, and best-effort HTTP/DNS. Use Value: L4 QoS with TCP/UDP port matching ensures jitter-free voice call setup and low-latency media playback without software intervention. |
| Wireless Routers | Cable Modems |
Use Scenario: Bridging 802.11n/g radio interface to wired LAN while isolating guest and private subnets. IC Role / Device Role / Timing Role: VLAN-aware switch enforcing policy-based forwarding between WLAN SSIDs and physical ports. Use Value: 16 VLANs with 12-bit ID learning enable simultaneous guest, IoT, and trusted network segmentation using single-hardware platform. | Use Scenario: Downstream DOCSIS data path aggregation with upstream return-path bridging to CMTS. IC Role / Device Role / Timing Role: High-reliability switching core handling bursty cable data traffic with multicast broadcast storm suppression. Use Value: Hardware multicast storm protection prevents control-plane overload during network topology changes or misconfigured STB devices. |
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 |
|---|---|---|---|
| ADM6996FCX-AD-R-1 | Same die, 128-pin LQFP but with full 6× PHY ports (no MAC-only Port 5); higher BOM cost due to extra PHY analog circuitry | Preferred where all six ports require PHY functionality (e.g., 6-port unmanaged switch) | Select when needing six physical copper interfaces instead of five PHY + one MAC uplink |
| ADM6995LCX-AD-R-1 | 5-port variant, lacks RMII interface, 1K MAC table, no L4 QoS or PPPoE identification, max packet length 1522 bytes | Suitable for cost-sensitive, non-PPPoE, single-VLAN residential gateways | Choose only if L4 classification, multicast storm protection, and >1522-byte frames are not required |
Compared with ADM6996FCX-AD-R-1, the LC variant trades one PHY for RMII flexibility and lower power; versus ADM6995LCX-AD-R-1, it adds critical L4 QoS, larger buffers, and robust multicast control essential for modern triple-play CPE.

FAQ
Does ADM6996LCX-AD-R-1 support IEEE 1588 Precision Time Protocol?
No. The ADM6996LCX-AD-R-1 does not implement PTP timestamping or hardware time synchronization. It supports standard IEEE 802.1p/Q for priority tagging and bandwidth shaping, but lacks the nanosecond-resolution timers and packet timestamp registers required for PTPv2 compliance.
Can the RMII interface operate at 100 Mbps full-duplex?
Yes. The RMII interface supports 100 Mbps full-duplex operation using a 50 MHz reference clock. It complies with the RMII v1.2 specification and requires no external PHY-direct connection to compatible host processors such as ARM926EJ-S or MIPS32 24KEc is supported.
What is the maximum operating junction temperature?
The ADM6996LCX-AD-R-1 has a maximum junction temperature of +85 °C, validated under worst-case 1.0 W power dissipation and 20 mm × 20 mm PCB copper area per Infineon's thermal design guidelines. Derating is required above ambient 70 °C for continuous operation.
Is external memory required for MAC table storage?
No. The 2,048-entry MAC address table is fully embedded in on-die SRAM. No external RAM or flash is needed for learning or forwarding operations. External EEPROM is only used for boot-time configuration loading (VLAN, QoS, security policies), not runtime table storage.
