EN5337QI Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from noise sources. Use a 50-ohm impedance-controlled trace for the RMII interface.
  • Implement proper thermal management by providing adequate airflow, using a heat sink if necessary, and ensuring the device is operated within the recommended temperature range (-40°C to 85°C).
  • The 1.2V supply should be decoupled with a 10uF capacitor, and the 2.5V supply should be decoupled with a 4.7uF capacitor. Ensure the power supplies are clean and stable, with minimal ripple and noise.
  • Use an oscilloscope to verify the RMII clock and data signals. Check the signal integrity, clock frequency, and data transmission rates. Ensure the RMII interface is properly terminated and the signal traces are properly routed.
  • Implement EMI shielding, use ESD protection devices, and ensure the PCB design follows EMI and ESD best practices. Use a common-mode choke and EMI filters as needed.
