KSZ9021RLI Frequently Asked Questions (FAQs)

  • The recommended PCB layout for the KSZ9021RLI is to use a 4-layer board with a solid ground plane, and to keep the analog and digital signals separate to minimize noise and interference.
  • The KSZ9021RLI can be configured for half-duplex or full-duplex operation by setting the appropriate registers. For half-duplex operation, set the TXEN and RXEN pins to toggle between transmit and receive modes. For full-duplex operation, set the TXEN pin high and the RXEN pin low.
  • The maximum cable length supported by the KSZ9021RLI is 100 meters, assuming a Category 5e or higher cable.
  • The KSZ9021RLI has a built-in power management feature that can be controlled through the PMEDEN pin. To implement power management, connect the PMEDEN pin to a GPIO pin on the host processor and use software to control the power state of the device.
  • The recommended clock frequency for the KSZ9021RLI is 25 MHz, but it can operate at frequencies up to 50 MHz.
