Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output traces short, using a solid ground plane, and minimizing noise coupling. Additionally, consider using a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure reliable operation over the entire operating temperature range (-40°C to 125°C), it's crucial to follow proper thermal management practices, such as providing adequate heat sinking, using thermal interface materials, and ensuring good airflow. Additionally, consider using a thermistor or temperature sensor to monitor the device temperature and adjust the operating conditions accordingly.
Operating the SCAN90CP02VY/NOPB at a lower input voltage than the recommended 3.3V may result in reduced performance, increased power consumption, and potential reliability issues. Operating at a higher input voltage may result in increased power consumption, heat generation, and potential damage to the device. It's essential to follow the recommended input voltage to ensure optimal performance and reliability.
To prevent electrostatic discharge (ESD) and latch-up, it's essential to follow proper handling and assembly procedures, such as using ESD-safe materials, grounding yourself before handling the device, and using ESD protection devices (e.g., TVS diodes) on the input and output pins. Additionally, consider using a latch-up prevention circuit or a power-on reset circuit to ensure reliable operation.
Operating the SCAN90CP02VY/NOPB at a clock frequency different from the recommended 100 MHz may result in changes to the device's performance, power consumption, and noise sensitivity. It's essential to consult the datasheet and perform thorough testing to ensure the device meets the required specifications at the desired clock frequency.
