Instructions for Use

  1. Power Supply:

    • Connect the VCC pin to a 3.3V ± 5% power supply.
    • Ensure a stable power supply to avoid operational issues.
  2. Grounding:

    • Connect all ground pins (GND) to a common ground plane to ensure proper signal integrity and reduce noise.
  3. MDI Connection:

    • Connect the MDI pins to an RJ45 connector for 10/100BASE-TX operation.
    • Ensure proper termination and cable quality to maintain signal integrity.
  4. Configuration:

    • Use the SPI or I2C interface to configure the device settings as required.
    • Refer to the datasheet for specific configuration registers and their functions.
  5. Low Power Mode:

    • To enter low power mode, set the appropriate control register bits.
    • This mode reduces power consumption but may affect performance.
  6. Wake-on-LAN:

    • Enable Wake-on-LAN by configuring the relevant registers.
    • Ensure the system supports this feature and is properly configured.
  7. EMI Considerations:

    • Follow recommended PCB layout guidelines to minimize electromagnetic interference (EMI).
    • Use decoupling capacitors close to the power pins to filter out noise.
  8. ESD Handling:

    • Handle the device with care to avoid electrostatic discharge (ESD).
    • Use ESD protection equipment when handling the device.
  9. Testing:

    • After assembly, perform initial tests to verify functionality.
    • Use diagnostic tools to check link status, data transmission, and error rates.
  10. Storage:

    • Store the device in a dry, cool environment to prevent moisture damage.
    • Follow anti-static storage practices to protect the device from ESD.
