DM9161AEP Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital signal traces separate and avoid crossing them over each other.
  • Use a high-quality decoupling capacitor (e.g., 10uF) close to the VCC pin, and ensure the power supply is stable and noise-free. Add a 10nF capacitor between VCC and GND for additional filtering.
  • The DM9161AEP supports cable lengths up to 100 meters (328 feet) for Fast Ethernet and 200 meters (656 feet) for Gigabit Ethernet, assuming a high-quality Category 5e or higher cable.
  • The DM9161AEP defaults to half-duplex mode. To enable full-duplex mode, set the FDEN (Full-Duplex Enable) pin high. For half-duplex mode, set FDEN low or leave it floating.
  • The recommended clock frequency is 25 MHz, but the DM9161AEP can operate with a clock frequency range of 20 MHz to 40 MHz.
