Texas Instruments provides a recommended PCB layout guide in their application note SLWC075, which includes guidelines for signal routing, power supply decoupling, and thermal management.
To ensure reliable operation, follow the recommended operating conditions, including power supply voltage, clock frequency, and thermal management. Additionally, consider using thermal simulation tools to analyze the device's thermal performance.
The maximum cable length supported by the DS90UH925QSQ/NOPB depends on the specific application and the type of cable used. As a general guideline, Texas Instruments recommends keeping the cable length below 10 meters for optimal performance.
To troubleshoot issues with the FPD-Link III interface, use a logic analyzer or oscilloscope to capture and analyze the signal waveforms. Check for proper signal termination, clock frequency, and data transmission rates. Consult the datasheet and application notes for specific troubleshooting guidelines.
Texas Instruments recommends using a combination of ceramic and electrolytic capacitors for power supply decoupling. A 10uF ceramic capacitor and a 22uF electrolytic capacitor are recommended for the 1.8V power supply, and a 10uF ceramic capacitor and a 47uF electrolytic capacitor are recommended for the 3.3V power supply.
