Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the 'High-Speed PCB Layout Guidelines' application note (SLYT685) for optimal performance.
To ensure signal integrity, use a controlled impedance PCB design, keep the signal traces short and away from noise sources, and use proper termination and filtering techniques. Also, follow the guidelines in the 'High-Speed Signal Integrity' application note (SLYT686).
The maximum cable length supported by the DS90UH925QSQX/NOPB depends on the specific application and the type of cable used. As a general guideline, the maximum cable length is around 10 meters for a 3.3V supply voltage and 5 meters for a 1.8V supply voltage. However, it's recommended to consult the datasheet and application notes for specific guidance.
To troubleshoot issues with the DS90UH925QSQX/NOPB, use a logic analyzer or oscilloscope to capture and analyze the signal waveforms. Check the power supply voltage, signal integrity, and termination. Consult the datasheet, application notes, and Texas Instruments' support resources for guidance.
The power consumption of the DS90UH925QSQX/NOPB depends on the specific application and operating conditions. The typical power consumption is around 150mW at 3.3V supply voltage and 100mW at 1.8V supply voltage. Consult the datasheet for specific power consumption values.
