Texas Instruments provides a recommended PCB layout in the DS90UH928QSQE/NOPB evaluation module documentation, which includes guidelines for signal routing, power supply decoupling, and thermal management.
To ensure reliable operation over the full temperature range, it is essential to 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 built-in clock generator has limitations on the maximum clock frequency, jitter, and phase noise. It is essential to review the datasheet and application notes to understand these limitations and ensure they meet the system requirements.
To troubleshoot issues with the deserializer, start by verifying the input signal quality, clock frequency, and power supply voltage. Use the device's built-in diagnostic features, such as the error detection and correction mechanisms, to identify the source of the issue. Consult the datasheet and application notes for guidance on troubleshooting and debugging techniques.
Using a lower clock frequency than recommended may result in reduced data transfer rates, while using a higher clock frequency may increase power consumption and reduce signal integrity. It is essential to review the datasheet and application notes to understand the implications of clock frequency selection on system performance.
