Texas Instruments provides a recommended PCB layout in the DS90UB901QSQ/NOPB evaluation module (EVM) user's guide, 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 using a heat sink and ensuring good airflow around the device. Additionally, the device should be operated within its specified temperature range (-40°C to 105°C).
The maximum cable length supported by the DS90UB901QSQ/NOPB depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths up to 10 meters at a data rate of 1 Gbps. For longer cable lengths, it is recommended to use repeaters or active cables.
To troubleshoot issues with the DS90UB901QSQ/NOPB, it is recommended to follow a systematic approach, including checking the power supply, clock signals, and data transmission. Additionally, Texas Instruments provides a troubleshooting guide in the datasheet and application notes that can be used to identify and resolve common issues.
The power consumption of the DS90UB901QSQ/NOPB depends on the specific application and operating conditions. However, the typical power consumption is around 1.2 W at a data rate of 1 Gbps. The device also has a low-power mode that can reduce power consumption to around 100 mW.
