Product details
Overview
AN983BLX-BG-T-V1 from Infineon Technologies is a PCI/Mini-PCI-to-Ethernet LAN controller IC integrating MAC, PHY interface (MII), and PCI bus interface in a single PQFP-128 package. It supports 10/100 Mbps Ethernet operation, Wake-on-LAN via Magic Packet, ACPI power management (D0–D3 states), and on-chip descriptor-based packet buffering with early transmit/receive interrupt capability. Used in embedded industrial PCs and legacy Mini-PCI slot-based network interface cards.
For engineers reviewing the AN983BLX-BG-T-V1 datasheet, AN983BLX-BG-T-V1 pinout, AN983BLX-BG-T-V1 application, or AN983BLX-BG-T-V1 equivalent, key selection criteria include MII PHY interface compatibility, PCI Rev 2.2 timing compliance, EEPROM-based configuration storage, LED control logic for link/activity status, and hardware-accelerated flow control in full-duplex mode.
Technical Context
The AN983BLX-BG-T-V1 implements a fully integrated PCI-to-Ethernet bridge with a compliant PCI 2.2 interface operating at 33 MHz, supporting both memory-mapped and I/O-mapped access. Its internal MAC layer handles IEEE 802.3 CSMA/CD protocol, frame filtering (unicast/multicast/broadcast), and automatic CRC generation/checking.
It interfaces to external 10/100BASE-TX PHYs via the standard Media Independent Interface (MII), with precise timing alignment per Figures 21–22 of the datasheet. The device includes dedicated CSR registers for PHY register access (via MDIO/MDC), transceiver reset control, and configurable LED drive modes (3- or 4-LED).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-Ethernet controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTL8139D-GR | Single-chip 10/100BASE-TX solution with integrated PHY; lacks MII interface and requires no external PHY. | Reduces BOM count but increases thermal load; not suitable where PHY isolation or mixed-speed PHY selection is required. | Select when minimizing component count and cost is prioritized over PHY flexibility or EMI isolation. |
| DM9000AEP | Non-PCI interface (ISA/SPI/parallel); requires external bus translation logic for PCI integration; lower power (120 mW typical). | Not pin- or register-compatible; demands custom driver and glue logic; better suited for microcontroller-based designs. | Select only for new designs targeting ultra-low power or non-PCI host architectures; not a drop-in replacement. |
Compared with RTL8139D-GR and DM9000AEP, the AN983BLX-BG-T-V1 uniquely preserves design flexibility through its MII interface, enables PHY vendor independence, and maintains strict PCI 2.2 timing margins-critical for stable operation in electrically noisy industrial backplanes.

FAQ
Does AN983BLX-BG-T-V1 include an integrated Ethernet PHY?
No. The AN983BLX-BG-T-V1 is a MAC+PCI controller only and requires an external 10/100BASE-TX PHY connected via the standardized MII interface. This architecture allows designers to select PHYs optimized for EMI performance, power, or specific feature sets (e.g., energy-efficient Ethernet).
What EEPROM types are supported for configuration storage?
The device supports standard I²C-compatible serial EEPROMs with 1K-bit (128×8) or 2K-bit (256×8) capacity, such as Atmel AT24C01/AT24C02 or Microchip 24LC01B/24LC02B. The EEPROM must be connected to SCL/SDA pins and programmed with valid MAC address, PHY ID, and CSR defaults per Section 8 of the datasheet.
Is the AN983BLX-BG-T-V1 compatible with modern PCIe-based systems?
No. It is strictly a PCI 2.2-compliant device and does not support PCIe electrical or protocol layers. Integration into PCIe systems requires a PCI-to-PCIe bridge chip (e.g., PLX PEX8311) and careful signal integrity validation due to timing skew between legacy PCI and high-speed serial lanes.
How is Wake-on-LAN implemented, and what conditions must be met?
Wake-on-LAN is implemented via hardware detection of the 6-byte preamble + 16 repetitions of the target MAC address (Magic Packet). The device must be in D3hot or D3cold state, have Vaux power applied, and have WOL enabled in CSR15 (bit 28). External PHY must also support and forward the Magic Packet to the MAC layer.
