Product details

Overview

ADM6996FCX-AD-T-1 from Infineon Technologies is a six-port 10/100 Mbps L2 Ethernet switch controller with integrated MDI(X) transceivers, hardware/software IGMP snooping, 16 VLAN support, Layer 4 QoS, and 802.1x security - deployed in ADSL routers and home gateways requiring full-duplex switching and multicast traffic management.

For engineers reviewing the ADM6996FCX-AD-T-1 datasheet, ADM6996FCX-AD-T-1 pinout, ADM6996FCX-AD-T-1 application, or ADM6996FCX-AD-T-1 equivalent, key selection criteria include RMII/MII interface compatibility, 128-pin LQFP footprint, 1784-byte max packet length, IGMP snooping capability, and 1.0W typical power consumption.

Technical Context

The ADM6996FCX-AD-T-1 implements a fully integrated switch fabric with five 10/100 PHY ports plus one RMII/MII MAC port, supporting both TX (10BASE-T) and FX (100BASE-FX) physical layer modes. It embeds a 2K-entry MAC address table with 4-layer hashing and supports learning up to 12-bit VLAN IDs.

Its L4 QoS engine classifies traffic by TCP/UDP destination port, IP protocol ID, and Ethernet type, enabling per-port ingress/egress bandwidth control scalable from 64 Kbps to 100 Mbps in 64 Kbps increments. The device also integrates hardware-based IGMP v1/v2 snooping and PPPoE packet filtering.

Key Specifications

Parameter	Value and Actual Design Meaning
Port Count	Six 10/100 Mbps ports: five PHY + one RMII/MII MAC interface
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 - meets IEEE 802.1q tagging requirements
Power Consumption	1.0 W typical - suitable for thermally constrained residential gateway designs
MAC Table Size	2,048 entries with 4-layer hash - reduces lookup latency and collision risk in dense network topologies
QoS Granularity	L4 classification by TCP/UDP port, IP protocol, and EtherType - enables precise multimedia traffic prioritization
Security Features	802.1x authentication, MAC address filtering ("Accept/Reject"), and multicast storm protection - enforces access control at edge

Pinout & Package

Package: 128-pin LQFP (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, lead-free, moisture-sensitive level 3.

Pin/Terminal	Circuit Role	Design Meaning
MDC/MDIO	Management Data Clock / I/O	IEEE 802.3-compliant serial interface for PHY register configuration and status readback
RMII_RXD[1:0], RMII_TXD[1:0]	Reduced MII Receive/Transmit Data	2-bit parallel interface for 10/100 Mbps MAC-to-processor connection, reducing pin count vs. full MII
LED[5:0]	Link/Activity Status Outputs	Dedicated open-drain outputs per port for real-time link/activity indication without external drivers
XTAL_IN/XTAL_OUT	Clock Oscillator Interface	Supports 25 MHz crystal for synchronous PHY timing and internal PLL generation
EEPROM_SCL/SDA	Serial EEPROM Interface	I²C-compatible bus for loading boot configuration, MAC address, and VLAN settings at power-up

Key Features

Feature	Design Value
Hardware IGMP Snooping	Reduces multicast flooding by dynamically updating forwarding tables based on IGMP join/leave messages - essential for VOD delivery
PPPoE Identification	Filters and forwards only valid PPPoE discovery and session packets - prevents DoS via malformed PPPoE frames
Port Mirroring	Enables non-intrusive traffic analysis on any port by duplicating frames to a designated monitoring port - supports network diagnostics
Advanced Filter Engine	Performs real-time L2–L4 header inspection (TCP/UDP port, IP protocol, EtherType) for ACL and QoS policy enforcement
Spanning Tree Protocol (STP)	Prevents Layer 2 loops in redundant topologies via IEEE 802.1D-compliant BPDU processing - ensures network stability

Applications

ADSL Routers

Home Gateways

Use Scenario: Aggregating DSL upstream with multiple LAN devices while managing VoIP, IPTV, and web traffic.

IC Role / Device Role / Timing Role: Central L2 switching controller coordinating PHY, MAC, and CPU interfaces with IGMP snooping for multicast video streams.

Use Value: 1784-byte packet support accommodates MPEG-TS encapsulation overhead; 1.0W power enables fanless enclosure design.

Use Scenario: Serving as the embedded switch in multi-service residential gateways with Wi-Fi, USB, and storage interfaces.

IC Role / Device Role / Timing Role: Traffic classifier and bandwidth shaper using L4 QoS to prioritize VoIP over best-effort data.

Use Value: Hardware IGMP snooping eliminates unnecessary multicast flooding, improving wireless backhaul efficiency.

Wireless Routers

Cable Modems

Use Scenario: Bridging 802.11n AP traffic to wired LAN segments with QoS-aware traffic shaping.

IC Role / Device Role / Timing Role: Switch fabric with RMII interface to host SoC, applying per-port bandwidth limits to prevent Wi-Fi congestion.

Use Value: 64 Kbps–100 Mbps scalable ingress/egress control enables precise SLA enforcement for ISP-managed devices.

Use Scenario: Providing switched Ethernet connectivity between DOCSIS modem core and customer premises equipment.

IC Role / Device Role / Timing Role: Secure edge switch enforcing 802.1x authentication and MAC-based access control before traffic enters the HFC network.

Use Value: Integrated 802.1x and "Accept/Reject" address filtering reduce need for external security co-processors.

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
ADM6996M-128	Includes IPv4/v6 DiffServ priority and TAG PRI replacement; same 128-LQFP package and pinout	Required for IPv6-ready deployments and advanced DSCP marking in carrier-grade CPE	Select when IPv6 QoS policy enforcement and VLAN tag manipulation are mandatory
RTL8306SD-GR	6-port 10/100 switch with 5+1 MII, no integrated PHY, lower power (0.65W), but lacks IGMP snooping and PPPoE filtering	Suitable for cost-sensitive, non-multicast-heavy applications where external PHYs are acceptable	Choose if system already uses discrete PHYs and multicast load is light; verify missing features against use case

Compared with ADM6996M-128, the ADM6996FCX-AD-T-1 omits IPv6 DiffServ but retains full IGMP snooping and PPPoE identification - making it optimal for IPv4-centric DSL/Cable CPE. Versus RTL8306SD-GR, it trades higher integration and security features for slightly higher power and BOM cost.

FAQ

Does ADM6996FCX-AD-T-1 support Jumbo Frames?

Yes, it supports a maximum frame size of 1784 bytes, which exceeds standard 1518-byte Ethernet frames and accommodates encapsulated VoIP and MPEG-TS payloads. This is implemented in hardware and requires no software configuration beyond buffer allocation in the host driver.

What interfaces does the device use to connect to an external processor?

The ADM6996FCX-AD-T-1 provides an RMII interface (2-bit data, REF_CLK, CRS_DV) and optional MII (4-bit data) for CPU-to-switch communication. It also supports SPI and I²C for configuration and status monitoring, with dedicated MDC/MDIO for PHY register access.

Is IGMP snooping implemented in hardware or firmware?

IGMP snooping is implemented entirely in hardware, with dedicated logic that intercepts IGMPv1/v2 join/leave messages and updates the forwarding database without CPU intervention. This ensures deterministic latency and zero impact on host processor load during multicast group changes.

Can the device operate without an external EEPROM?

Yes - default configuration is stored in internal ROM, allowing basic operation without EEPROM. However, features like custom MAC address, VLAN setup, and port mirroring require external EEPROM (I²C interface) for persistent storage across power cycles.
