Instructions for Use:
Power Supply Connections:
- Connect VCC to a stable 1.2V supply.
- Connect VDD to a stable 3.3V supply.
- Ensure proper decoupling capacitors are placed close to the power pins.
Reset Pin (RSTB):
- The reset pin is active low. Apply a low pulse to this pin to reset the device.
Clock Input (CLK):
- Provide a 25 MHz or 50 MHz clock signal to the CLK pin for proper operation.
Interface Configuration:
- Configure the interface mode (RGMII, RMII, MII, TBI) through the appropriate control registers.
LED Control:
- Use the LED control registers to configure the link/activity LEDs.
Low Power Mode:
- Enter low power mode by setting the appropriate bit in the control register.
JTAG Boundary-Scan:
- Use the JTAG interface for boundary-scan testing and debugging.
ESD Handling:
- Handle the device with care to avoid ESD damage. Use ESD-safe tools and workstations.
Mounting and PCB Layout:
- Follow recommended PCB layout guidelines to ensure optimal performance and reliability.
Thermal Management:
- Ensure adequate heat dissipation by following the thermal design guidelines provided in the datasheet.
