Design Considerations

  • What is the reference Ethernet transformer of the AX88772A demo board?

    The reference Ethernet transformer on the AX88772A demo board is the Bothhand LU1S041X LF (Turns Ratio 1CT:1CT, Auto-MDIX) single RJ-45 connector module with integrated 10/100 BASE-TX magnetic. Please refer to Section 4 of AX88x72A USB-to-LAN Application Design Note for the detailed Ethernet magnetic circuit information. You can download it from AX88772A Application Design & Layout Guide Download web page directly.

  • What are the specification of 12MHz & 25MHz reference crystals of AX88772A demo board?

    The 12MHz/25MHz crystal signals of AX88772A board should be winthin (12MHz +- 50ppm)/(25MHz +- 50ppm) respectively. Please refer to Section 3 of AX88x72A USB-to-LAN Application Design Note for the detailed 12MHz/25MHz crystal circuits information. You can download it from AX88772A Application Design & Layout Guide Download web page directly.

  • What kind of EEPROM is supported by AX88772A?

    AX88772A supports 16-bit mode 93C56 or 93C66 EEPROM.

  • Can I remove the EEPROM from the AX88772A application?

    No, the AX88772A EEPROM content includes important hardware initialization data like USB descriptors, product strings, serial number, etc. This configuration data will be used during the AX88772A's hardware initialization for normal operation.

  • How do I program the AX88772A EEPROM?

    AX88772A supports some default settings inside chip hardware to enable it to communicate with USB host controller during enumeration when the AX88772A EEPROM is blank (prior to being programmed). The default settings inside chip facilitate users to update the EEPROM content through a Windows PC during R&D validation process or program a blank EEPROM mounted on target system PCB during manufacturing process.
    ASIX Electronics provides a Windows SROM Programming tool for users to easily program the Serial EEPROM of AX88772A on a typical Windows XP/2000 PC. This AX88772A WinXP/2K SROM Programming Tool supports to customize the MAC address, Serial Number, Vendor ID and Product ID, etc. for AX88772A based application systems in mass production.

    Alternatively, users can pre-program the blank EEPROM on a 3rd Party Universal Programmer before soldering the EEPROM onto the AX88772A application device. It is recommended that users assign a unique MAC address in the EEPROM for every AX88772A device.

    Also if users plan to use a Windows PC to test AX88772A-based devices repeatedly during mass production, it is recommended that the same serial number be assigned to the EEPROM for every AX88772A device. However, a different serial number should be assigned in the EEPROM for every AX88772A device if users need to install more than one AX88772A device on the same platform.

    Please contact ASIX's sales (sales@asix.com.tw) to get the AX88x72A EEPROM User Guide for more details.

  • Do we need to register our own VID/PID for our AX88772A based application systems or can we use the ASIX's VID/PID?

    It depends on your product applications and target market which may vary case by case. Below are some general guidelines on whether one can use ASIX's VID/PID or use its own registered VID/PID.
    1. Case where it is OK to use ASIX Electronics's VID (0B95h) and PID (772Ah):

    (1) Your AX88772A-based application works with the standard AX88772A drivers provided by ASIX without any modification to the driver.

    (2) You are not concerned from a business and product marketing perspective about sharing the same VID and PID on your products as ASIX's other customers.

    (*Note) Please inform ASIX by emailing us at sales@asix.com.tw beforehand if you would like to use ASIX Electronics VID and PID for your products.

    *Note: This can avoid your end customers from downloading the standard AX88772A driver from the ASIX website which may not be compatible with your device drivers.

    2. Cases requiring you to use your own VID and PID

    (1) Your AX88772A based application system doesn't work with the AX88772A standard drivers released on this website and your target application system (such as USB dongle or docking station) allows end customers to update the standalone AX88772A driver by themselves after sales. In this case, you MUST assign your own unique VID and PID to your AX88772A based devices.

    (2) For brand name products, you probably don't want your AX88772A-based devices to be compatible with other companies' AX88772A-based devices. In this case, you should consider assigning your own unique VID and PID for your AX88772A based devices.

    You can register your own VID from USB Implementers Forum, Inc. and define the PID based on your company rules. If you have any problems, please contact ASIX's sales (sales@asix.com.twa>) for further support.

  • How do I register a Vendor ID from USB-IF?

    If you are a new USB product developer looking to get a Vendor ID for your company, you can register a Vendor ID from USB Implementers Forum, Inc. Please visit the USB-IF web site for details.

  • Do I have to assign a unique MAC address to every AX88772A based devices?

    Yes, every Ethernet device must have a unique MAC address. You should always assign a unique MAC address in the AX88772A EEPROM.

  • How do I register a MAC/Ethernet address from IEEE-SA?

    You must first have an OUI or an IAB, to which you then append 24 or 12 bits respectively, in a way that makes the resulting 48-bit number unique. Your 24 or 12 bits must be unique within your organization, which will require coordination among all the users of your organization's OUI or IAB. Please visit the IEEE-SA web site for details.

  • Do I have to assign a unique serial number to every AX88772A based device?

    No, it depends on the real requirement of your AX88772A target application. If your end customer may need to install more than one AX88772A-based device on your target application, you should assign a different serial number in the EEPROM for every AX88772A device.
    If your target application always uses one AX88772A device, you can consider assigning the same serial number in the EEPROM for every AX88772A device for easy maintenance in mass production, especially if you plan to use a Windows PC to test AX88772A based devices repeatedly during the mass production test.

  • Did the AX88772A pass the USB-IF compliant certification?

    Yes, AX88772A demo board was certified by USB-IF.

  • Are AX88772A Windows drivers qualified by the WHQL compliant certification?

    Yes, all AX88772A Windows 10/8.x7/Vista/XP 32-bit/64-bit drivers were qualified by Microsoft WHQL certification.

  • Does the AX88772A Windows driver support the WOL function in S4 (Hibernate)/S5 (Shutdown) mode?

    The answer depends on whether the USB host controller supports the S4/S5 wake-up function or not since the WOL function of AX88772A USB to LAN devices should be supported on both AX88772A and the USB host controller. Many USB host controllers don't support the WOL function in S4 (Hibernate)/S5 (Shutdown) mode.

  • Can the AX88772A be connected to another Ethernet MAC controller through a MII interface?

    No, the AX88772A doesn't support the MII interface. In this case, you can implement AX88172A with MII interface on your target application. Please contact ASIX's sales (sales@asix.com.tw) for further support.

  • How to open the gerber files of AX88772A demo board?

    You can open the gerber files of AX88772A demo board by running ORACLE's AutoVue Evaluation Revision tool (30 days evaluation date). Please visit ORACLE's web site for more details.

  • How to open the PowerPCB PCB layout file of AX88772A demo board?
