A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the edge of the board to minimize signal reflections. A minimum of 10 mils of clearance around the device is recommended to ensure proper heat dissipation.
The device is rated for operation up to 85°C. To ensure reliable operation, ensure good airflow around the device, use a heat sink if necessary, and follow proper thermal design guidelines. Additionally, reduce the transmit power or duty cycle to minimize self-heating.
The recommended input signal level is between -10 dBm and 0 dBm. Signals above 0 dBm may cause compression and distortion, while signals below -10 dBm may not be detectable.
Use a signal generator and oscilloscope to verify the input signal. Check the device's power supply and ground connections. Verify that the device is properly terminated and that the PCB layout is correct. Consult the datasheet and application notes for additional troubleshooting guidance.
While the AFBR-5805TZ is optimized for IEEE 802.3bt applications, it can be used in other applications with proper design and testing. However, the device's performance and reliability may vary depending on the specific application.
