LAN8820-ABZJ 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 signals separate, and use a common mode filter to reduce EMI.
  • Use the LAN8820-ABZJ's register configuration to set the desired PHY mode. For example, to set 1000 Mbps mode, set register 0x10 to 0x03 and register 0x11 to 0x01. Refer to the datasheet for specific register settings.
  • The LAN8820-ABZJ supports cable lengths up to 100 meters for 10/100 Mbps and up to 70 meters for 1000 Mbps, assuming a Category 5e or higher cable.
  • Use a logic analyzer or oscilloscope to monitor the LAN8820-ABZJ's signals, such as the TX_CLK and RX_CLK. Check the PHY status registers for error counters and link status. Verify that the PCB layout and component selection meet the datasheet recommendations.
  • While the LAN8820-ABZJ supports standard RJ-45 connectors, using a non-standard connector or cable may affect signal integrity and reliability. It is recommended to use a standard RJ-45 connector and Category 5e or higher cable to ensure optimal performance.
