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.
The AX99100QF is a highly configurable device. You can configure it using the SPI interface to select the desired Ethernet protocol, such as IEEE 802.3u or IEEE 802.1Q. Refer to the datasheet for specific register settings.
The AX99100QF supports cable lengths up to 100 meters, as per the IEEE 802.3u standard. However, the actual cable length may vary depending on the specific application and environment.
Use a logic analyzer or a protocol analyzer to capture and analyze the Ethernet traffic. Check the device's registers and status bits to identify the source of the issue. Also, ensure that the PCB layout and power supply are within the recommended specifications.
Yes, the AX99100QF is rated for industrial temperature range operation. However, ensure that the device is properly powered and the PCB is designed to withstand the temperature range.
