LAN9353I/PT 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 common mode filter and a shielded RJ-45 connector to reduce EMI.
  • The LAN9353I/PT can be configured for half-duplex or full-duplex operation through the MDIO interface. Set the duplex mode by writing to the BMCR register (0x00) and setting the DUPLEX bit (bit 10) accordingly.
  • The LAN9353I/PT supports cable lengths up to 100 meters, as per the IEEE 802.3 standard. However, the actual cable length may vary depending on the specific application and environment.
  • The LAN9353I/PT has a built-in power management feature that can be controlled through the PMD register (0x10). Set the PWDN bit (bit 15) to 1 to power down the device. You can also use the Wake-On-LAN (WOL) feature to wake up the device from power-down mode.
  • The LAN9353I/PT has a maximum junction temperature of 150°C. Ensure good airflow around the device and use a heat sink if necessary. The device also has a thermal shutdown feature that activates when the junction temperature exceeds 160°C.
