Texas Instruments provides a recommended PCB layout in the DS90UH927QSQE/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 test patterns are designed for basic debugging and may not cover all possible scenarios. For more comprehensive testing, it is recommended to use external test equipment or develop custom test patterns using the device's programming interface.
To optimize power consumption, consider using the device's power-down modes, reducing the clock frequency, and optimizing the signal transmission rate. Additionally, use the device's built-in power management features, such as dynamic voltage scaling and clock gating.
To mitigate EMI and RFI, follow proper PCB layout and shielding techniques, use EMI filters and absorbers, and ensure proper grounding and decoupling. Additionally, consider using the device's built-in EMI reduction features, such as spread spectrum clocking.
