A good PCB layout practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the signal traces short and away from noise sources. TI also recommends using a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The AM26LV31EIRGYRG4 requires a single 3.3V power supply. Ensure that the power supply is clean and regulated, and that the device is properly configured by setting the correct voltage on the VCC pin and configuring the EN pin according to the datasheet.
The AM26LV31EIRGYRG4 can achieve data rates up to 100 Mbps, but the actual data rate may vary depending on the system design, PCB layout, and cable quality.
Use a logic analyzer or oscilloscope to monitor the signal waveforms and verify that the device is receiving the correct input signals. Check the power supply voltage, ground connections, and signal integrity. Consult the datasheet and application notes for troubleshooting guidelines.
The AM26LV31EIRGYRG4 is rated for operation from -40°C to 85°C. However, the device's performance and reliability may degrade at higher temperatures. Consult the datasheet and application notes for thermal management guidelines.
