Product details
Overview
ADM6996LHX-AC-T-1 from Infineon Technologies (formerly ADMtek) is a single-chip 6-port 10/100 Mb/s Ethernet switch controller integrating six 10/100 PHYs, MII/GPSI interfaces, VLAN tagging, priority-based QoS, and embedded memory for address learning and forwarding. It supports full/half-duplex operation, auto-MDIX, jabber protection, and link polarity detection. Used in managed SOHO switches and embedded network appliances requiring compact Layer 2 switching.
For engineers reviewing the ADM6996LHX-AC-T-1 datasheet, ADM6996LHX-AC-T-1 pinout, ADM6996LHX-AC-T-1 application, or ADM6996LHX-AC-T-1 equivalent, key selection criteria include integrated PHY count, MII/GPSI interface compatibility, VLAN and QoS register mapping, and 48-pin LQFP package thermal and routing constraints.
Technical Context
The ADM6996LHX-AC-T-1 implements a fully integrated Layer 2 switching engine with hardware-based address learning (1K MAC entries), aging (300–1500 sec configurable), and store-and-forward packet handling. Its six independent 10/100 PHY blocks support simultaneous 10BASE-T and 100BASE-TX operation per port, each with adaptive equalization, NRZI/NRZ decoding, and carrier sense logic.
It features dual host interfaces: a 4-bit GPSI (7-wire serial) for microcontroller management and a standard 16-bit MII for direct connection to external MACs. Clock synthesis is internal (25 MHz crystal input), eliminating need for external PLLs, and EEPROM configuration (via 2-wire I²C-compatible interface) enables boot-time parameter loading including VLAN maps and priority tables.

Pinout & Package
ADM6996LHX-AC-T-1 is housed in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across five functional groups: twisted-pair PHY I/O (TX+/−, RX+/− per port), MII/GPSI data/control lines, LED drivers, EEPROM interface (SCL/SDA), power/ground, and configuration strapping pins (e.g., BOOT[1:0], MODE).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX0P/TX0N | Port 0 differential transmit output | Drives 100BASE-TX signal onto twisted pair; requires 100 Ω termination and magnetics |
| RX0P/RX0N | Port 0 differential receive input | Accepts 100BASE-TX input; includes adaptive equalizer and timing recovery |
| MII_D0–MII_D15 | MII parallel data bus | 16-bit bidirectional data path for external MAC communication at 25 MHz |
| GPSI_DATA[3:0] | GPSI serial data bus | 4-bit multiplexed command/data interface for low-pin-count MCU control |
| LED0–LED5 | Per-port activity/link status outputs | Open-drain CMOS outputs driving external LEDs; configurable via register |
| VDDIO/VSS | I/O power and ground | 3.3 V supply for digital I/O; dedicated ground plane required for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6-port PHY + switch fabric | Eliminates need for six discrete PHY ICs and external switch ASIC; reduces BOM and PCB area by >40% |
| Auto MDI/MDI-X on all ports | Automatically detects cable type and configures port polarity-no manual crossover or DIP-switch setup |
| VLAN and QoS support | Hardware-enforced port-based VLANs and 802.1p priority tagging enable traffic segregation without software overhead |
| EEPROM-based configuration | Boot-time initialization from external 2-kbit EEPROM allows field-updatable settings without firmware reflash |
| Jabber and link test functions | Hardware-level jabber detection prevents network flooding; link test verifies cable integrity up to 100 m |
Applications
| SOHO Managed Switch | Industrial Ethernet Gateway |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6-port Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E6060-B0-LF | 5-port 10/100 switch with external PHY requirement; no integrated PHYs | Requires 5 discrete PHYs and external clock; higher BOM cost and layout complexity | Select when needing Marvell SDK support or existing board reuse with external PHY architecture |
| Realtek RTL8306SD-GR | 6-port 10/100 switch with integrated PHYs but only MII interface (no GPSI) | Lacks GPSI serial management; requires 16-bit host interface and larger PCB footprint | Select when host MCU has MII available and EEPROM-less boot is acceptable |
Compared with ADM6996LHX-AC-T-1, the Marvell 88E6060 demands external PHYs and increases design complexity, while the Realtek RTL8306SD omits GPSI-limiting low-pin-count MCU integration. ADM6996LHX-AC-T-1 uniquely balances integration, dual-interface flexibility, and compact LQFP packaging for space-constrained edge nodes.

FAQ
Does ADM6996LHX-AC-T-1 support Gigabit Ethernet?
No. ADM6996LHX-AC-T-1 supports only 10BASE-T and 100BASE-TX per port, compliant with IEEE 802.3u. It lacks 1000BASE-T PHY circuitry, MII extensions (GMII/RGMII), or bandwidth capacity for Gigabit operation. Maximum aggregate throughput is 1.2 Gbps in full-duplex mode across six ports.
What crystal frequency is required for the ADM6996LHX-AC-T-1?
A 25.000 MHz fundamental-mode crystal is required on the XTAL1/XTAL2 pins. The internal PLL multiplies this to generate all necessary clocks-including 25 MHz for MII, 2.5 MHz for GPSI, and 125 MHz for internal switching fabric-eliminating need for external clock generators.
Can ADM6996LHX-AC-T-1 operate without an external EEPROM?
Yes, but with limited functionality. Strapping pins (BOOT[1:0]) allow default register initialization without EEPROM; however, VLAN maps, priority tables, and port-specific settings must be loaded via GPSI/MII after power-up, increasing host firmware complexity and boot time.
Is the 48-pin LQFP package lead-free and RoHS-compliant?
Yes. ADM6996LHX-AC-T-1 is manufactured in a lead-free, RoHS-compliant 48-pin LQFP package (Pb-free solder profile compatible with JEDEC J-STD-020D). The exposed thermal pad is electrically connected to VSS and must be soldered to a solid ground plane for thermal and EMI performance.
