Product details
Overview
ADM6996FHX-AC-T-1 from Infineon Technologies is a 12-port Ethernet switch controller IC supporting IEEE 802.3ab (1000BASE-T), 802.3u (100BASE-TX), and 802.3 (10BASE-T) standards, with integrated 12×10/100/1000 Mbps PHYs, embedded 128 KB packet buffer RAM, and full non-blocking wire-speed switching at line rate. It serves as the central Layer 2 switching engine in managed industrial Ethernet edge switches.
For engineers reviewing the ADM6996FHX-AC-T-1 datasheet, ADM6996FHX-AC-T-1 pinout, ADM6996FHX-AC-T-1 application, or ADM6996FHX-AC-T-1 equivalent, key selection criteria include integrated PHY count, QFP-128 package compatibility, MII/RMII/SerDes interface flexibility, embedded memory size, and IEEE 802.1Q VLAN support for deterministic network segmentation.
Technical Context
This switch controller implements a fully integrated 12-port Gigabit Ethernet switch fabric with hardware-based forwarding decision logic, supporting cut-through and store-and-forward modes. It includes an embedded ARM7TDMI CPU core for management plane execution and supports SNMPv1/v2c/v3, HTTP, Telnet, and CLI interfaces.
The device features configurable Quality of Service (QoS) with eight priority queues per port, IEEE 802.1p tagging, and rate limiting per ingress/egress port. Its SerDes interface supports SGMII to external PHYs or MACs, while internal PHYs comply with IEEE 802.3 specifications including auto-negotiation and energy-efficient Ethernet (EEE) mode.
