Instructions for Use
Power Supply:
- Connect the 3.3V supply voltage to the VCC pin.
- Ensure the power supply is stable and within the specified range (3.3V ± 5%).
Ground Connection:
- Connect all ground pins (GND) to a common ground plane.
MII Interface:
- Connect the MII interface pins to your microcontroller or FPGA as per the pinout diagram.
- Refer to the MII interface timing and signal descriptions in the datasheet.
Ethernet Interface:
- Connect the RJ45 connector to the MDI (Medium Dependent Interface) pins.
- Use an integrated transformer or external transformer as required.
Configuration:
- Configure the device using the control registers via the MII interface.
- Set the desired data rate (10 Mbps or 100 Mbps) and enable auto-negotiation if needed.
Power Management:
- To enter low power mode, set the appropriate register bit.
- To wake up from low power mode, use the wake-up signal or reset the device.
Testing:
- After setup, test the link status and data transmission.
- Use network testing tools to verify the connection and performance.
Handling:
- Handle the device with care to avoid ESD damage.
- Store the device in an ESD-safe environment when not in use.
For detailed information, refer to the datasheet and application notes provided by the manufacturer.
