Texas Instruments provides a recommended PCB layout in the DS90UA101 application note (SLUUAC5) which includes guidelines for component placement, routing, and thermal management.
To ensure reliable operation in high-temperature environments, it is recommended to follow the thermal management guidelines in the datasheet, including providing adequate heat sinking and airflow, and using thermal interface materials as needed.
The maximum cable length supported by the DS90UA101TRTVRQ1 depends on the specific application and the type of cable used. However, as a general guideline, Texas Instruments recommends keeping the cable length below 10 meters to ensure reliable operation.
While the DS90UA101TRTVRQ1 is specified to operate with a 1.8V input voltage, it can tolerate a range of input voltages from 1.62V to 1.98V. However, operating the device outside of the recommended voltage range may affect its performance and reliability.
Texas Instruments provides a troubleshooting guide in the DS90UA101 application note (SLUUAC5) which includes steps to identify and resolve common issues, such as signal integrity problems, power supply issues, and thermal management issues.
