KSZ9021RN Frequently Asked Questions (FAQ)
-
The recommended PCB layout for the KSZ9021RN 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 KSZ9021RN 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 accordingly. For full-duplex operation, set the TXEN pin high and the RXEN pin low.
-
The maximum cable length supported by the KSZ9021RN is 100 meters, assuming a Category 5e or higher cable.
-
To troubleshoot issues with the KSZ9021RN, check the power supply voltage, clock frequency, and signal integrity. Use an oscilloscope to verify the signal waveforms and check for any signal distortion or noise.
-
The KSZ9021RN is designed to support standard Ethernet protocols (10/100 Mbps). Using a non-standard protocol may require custom firmware development and is not recommended.
