Product details
Overview
ADM6996IX-AD-R-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 traffic management.
For engineers reviewing the ADM6996IX-AD-R-1 datasheet, ADM6996IX-AD-R-1 pinout, ADM6996IX-AD-R-1 application, or ADM6996IX-AD-R-1 equivalent, key selection criteria include RMII/MII interface compatibility, 1784-byte maximum packet length, 2K MAC address table depth, 1.0W typical power consumption, and 128-pin LQFP package footprint constraints.
Technical Context
The ADM6996IX-AD-R-1 implements a fully integrated L2 switching engine with hardware-accelerated IGMP snooping, 4-layer hashing for MAC address lookup, and configurable ingress/egress bandwidth control (64K–100Mbps in 64K steps). It supports both MII and RMII host interfaces and includes dedicated hardware for PPPoE packet identification and TCP/UDP destination port filtering.
Its architecture integrates five 10/100 PHYs plus one 10/100 MAC port, a learning handler with 2K address table capacity, multicast broadcast storm protection, and dual-mode VLAN tagging (802.1q with 12-bit ID support). The device uses a PLL-based clock system and supports external EEPROM configuration via I²C-compatible interface.

IC Role / Device Role / Timing Role: Secure bridging element enforcing 802.1x authentication for managed devices and filtering unauthorized MAC addresses. Use Value: "Accept/Reject" MAC filtering blocks rogue DHCP servers and prevents LAN-side DoS attacks. |
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 RMII interface, 1K MAC table, no TCP/UDP port filtering, 1.3W power | Targeted at cost-sensitive legacy ADSL designs without advanced QoS requirements | Select when migrating from older ADM6995L and RMII is not needed |
| RTL8306SD | 6-port 10/100 switch with MII only, no IGMP snooping hardware, 1K MAC table, 1.2W | Used in basic SOHO switches where multicast optimization is handled externally | Choose for simpler designs where CPU offload for IGMP is unnecessary |
Compared with ADM6996LC and RTL8306SD, the ADM6996IX-AD-R-1 delivers superior multicast efficiency via hardware IGMP snooping, finer-grained QoS with L4 port awareness, and lower thermal output-making it optimal for next-generation multimedia gateways where CPU offload and power density matter.

FAQ
What is the maximum supported packet size for ADM6996IX-AD-R-1?
The ADM6996IX-AD-R-1 supports a maximum frame length of 1784 bytes, which exceeds standard Ethernet's 1518-byte limit and accommodates jumbo frames used in IPTV transport stream delivery and large-file transfers without fragmentation.
Does ADM6996IX-AD-R-1 support both MII and RMII host interfaces?
Yes-ADM6996IX-AD-R-1 provides dual-mode MAC interface support: full MII (16-bit data path) and reduced-pin RMII (2-bit data path), enabling direct connection to a wide range of MIPS, ARM9, and proprietary SoCs without glue logic.
How does hardware IGMP snooping improve performance in IPTV deployments?
Hardware IGMP snooping eliminates multicast flooding by building dynamic forwarding tables from IGMP reports-reducing unnecessary LAN traffic by up to 70% and preventing bandwidth starvation on shared DSL links during concurrent HD video sessions.
Is external EEPROM required for ADM6996IX-AD-R-1 configuration?
Yes-configuration parameters including MAC addresses, VLAN settings, and port mirroring rules are loaded at power-up via I²C-compatible SCL/SDA pins from an external serial EEPROM; absence of EEPROM results in default factory settings with limited functionality.
