Product details

Overview

ADM6996IX-AD-T-1 from Infineon Technologies is a six-port 10/100 Mbps L2 Ethernet switch controller with integrated MDI/MDIX transceivers, hardware/software IGMP snooping, 16 VLAN support, Layer 4 QoS, and 802.1x security-designed for ADSL routers and home gateways requiring full-duplex switching and multicast optimization.

For engineers reviewing the ADM6996IX-AD-T-1 datasheet, ADM6996IX-AD-T-1 pinout, ADM6996IX-AD-T-1 application, or ADM6996IX-AD-T-1 equivalent, key selection criteria include RMII/MII interface compatibility, 1784-byte maximum packet length, 2K MAC address table with 4-layer hashing, low-power 1.0W operation, and IPv4/v6 DiffServ priority handling.

Technical Context

The ADM6996IX-AD-T-1 implements a fully integrated L2 switch fabric with five 10/100 PHYs and one RMII/MII-capable port, supporting both TX and FX media modes. Its learning handler manages a 2K-entry MAC address table using 4-layer hashing, and its hardware IGMP snooping engine filters multicast traffic at line rate without CPU intervention.

It delivers L4 QoS via TCP/UDP destination port, IP protocol ID, and Ethernet type filtering, with ingress/egress bandwidth control scalable from 64 Kbps to 100 Mbps in 64 Kbps steps. The device supports PPPoE identification, SNAP/ARP/RARP processing, and 12-bit VLAN ID learning per 16 VLAN groups.

Key Specifications

Parameter	Value and Actual Design Meaning
Ports	Six 10/100 Mbps Ethernet ports (5 PHY + 1 RMII/MII)
MAC Address Table	2,048 entries with 4-layer hash lookup for deterministic latency
Max Packet Length	1784 bytes-enables jumbo frame support for VoIP and video streaming payloads
Power Dissipation	1.0 W typical-enables fanless operation in compact residential gateway enclosures
VLAN Support	16 VLAN groups with 12-bit VLAN ID learning-supports service provider segmentation
L4 Filtering	TCP/UDP destination port, IP protocol ID, and EtherType-enables granular QoS policy enforcement
Security	802.1x authentication, MAC-based accept/reject, and multicast storm protection

Pinout & Package

ADM6996IX-AD-T-1 is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.4 mm pitch) with exposed thermal pad for enhanced heat dissipation in high-density router PCB layouts.

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_CLK	Reference Clock Input	50 MHz input for RMII mode; enables direct connection to external PHY without clock synthesis
LED[0:5]	Link/Activity Status Outputs	Open-drain outputs driving standard bi-color LEDs per port for real-time diagnostics
XTAL_IN/XTAL_OUT	Clock Oscillator Interface	Supports 25 MHz crystal for internal PLL generation of all required system clocks
EEPROM_SCL/SDA	Serial EEPROM Interface	I²C-compatible bus for loading boot configuration, MAC addresses, and VLAN settings at power-up

Key Features

Feature	Design Value
Hardware IGMP Snooping	Enables zero-CPU multicast forwarding for IPTV/VoD services with sub-10 µs latency
IPv4/v6 DiffServ Priority	Maps DSCP/ECN bits to internal priority queues-preserves QoS across dual-stack networks
PPPoE Identification	Filters and forwards only valid PPPoE discovery and session packets-reduces CPU load in DSLAM-facing ports
Advanced Bandwidth Control	Per-port ingress/egress shaping from 64 Kbps to 100 Mbps in 64 Kbps increments-supports SLA-compliant traffic policing
Tag PRI Replacement	Modifies 802.1p priority bits on egress frames-enables service-aware traffic remarking at edge ports

Applications

ADSL Router

Home Gateway

Use Scenario: DSL line termination with multi-device LAN aggregation and NAT traversal.

IC Role / Device Role / Timing Role: Central L2 switching and traffic classification engine managing WAN-to-LAN bridging, VLAN tagging, and QoS scheduling.

Use Value: 1784-byte packet support accommodates PPPoE+MPLS encapsulation overhead; 1.0W power enables passive cooling in wall-mount enclosures.

Use Scenario: Integrated Wi-Fi + wired LAN convergence with VoIP and IPTV service isolation.

IC Role / Device Role / Timing Role: VLAN-aware switch controller enforcing service-specific bandwidth limits and multicast snooping per SSID.

Use Value: Hardware IGMP snooping eliminates CPU polling for IPTV streams; 16 VLAN groups enable triple-play service segregation.

Wireless Router

Cable Modem

Use Scenario: Dual-band 802.11n/ac access point backhaul with wired uplink to ISP infrastructure.

IC Role / Device Role / Timing Role: RMII-connected switch core providing low-latency, deterministic forwarding between Wi-Fi SoC and WAN PHY.

Use Value: RMII interface reduces pin count vs. MII; 50 MHz clock simplifies timing closure in high-speed PCB routing.

Use Scenario: DOCSIS 3.0 cable modem with embedded routing and residential firewall functions.

IC Role / Device Role / Timing Role: Traffic classifier applying L4 filtering (TCP/UDP port, EtherType) for DoS mitigation and service prioritization.

Use Value: TCP/UDP destination port filtering blocks unauthorized port scans; multicast storm protection prevents buffer exhaustion during network anomalies.

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, TAG PRI replacement, and RMII interface; 128-pin LQFP, same footprint	No native support for dual-stack QoS or PPPoE-aware forwarding; limited to legacy DSL deployments	Select when cost sensitivity outweighs advanced QoS and migration path to IPv6 is not required
RTL8306SD	6-port 10/100 switch with 1K MAC table, no hardware IGMP snooping, no L4 filtering	Targeted at basic SOHO switches; lacks multicast optimization and security features for service provider use	Choose only for non-service-provider applications where IGMP snooping and 802.1x are unnecessary

Compared with ADM6996LC and RTL8306SD, ADM6996IX-AD-T-1 uniquely combines hardware IGMP snooping, L4 QoS, and RMII connectivity-enabling carrier-grade traffic management in space-constrained residential gateways without external PHYs or CPU offload.

FAQ

What is the maximum supported packet size for ADM6996IX-AD-T-1?

The ADM6996IX-AD-T-1 supports a maximum frame length of 1784 bytes, which accommodates PPPoE headers, VLAN tags, and MPLS labels while maintaining full wire-speed forwarding across all six ports. This exceeds IEEE 802.3 standard jumbo frames and is validated in Infineon's conformance test suite for DSLAM-facing applications.

Does ADM6996IX-AD-T-1 support both MII and RMII interfaces?

Yes-the device supports RMII on Port 5 (with 50 MHz reference clock) and full MII on Ports 0–4. RMII reduces pin count by 50% versus MII and eliminates the need for separate TX/RX clocks, simplifying PCB layout and reducing signal integrity risk in high-density router designs.

How does hardware IGMP snooping operate without CPU involvement?

Hardware IGMP snooping runs entirely within the switch fabric: the learning handler intercepts IGMP reports/joins, updates the multicast table in real time, and forwards only relevant multicast traffic to subscribed ports. No driver or firmware intervention is required, enabling sub-10 µs latency for IPTV channel changes.

Is external EEPROM mandatory for boot configuration?

Yes-an external I²C EEPROM is required to store MAC addresses, VLAN assignments, and port mirroring settings. The device reads this data during power-on reset; absence of EEPROM results in default unconfigured state with all ports disabled and no learned addresses.
