A good PCB layout for the FDC3535 involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, using a shielded cable for the USB interface can help reduce EMI.
To optimize power consumption, use the device's low-power modes, such as the suspend mode, and adjust the clock frequency to the lowest required for the application. Additionally, consider using a low-dropout regulator to minimize power loss.
The FDC3535 has a maximum junction temperature of 150°C. Ensure reliable operation by providing adequate heat sinking, using a thermal pad or heat sink, and keeping the device away from heat sources. Monitor the device's temperature using the thermal monitoring feature.
Implement a robust USB interface by following the USB specification, using a shielded cable, and ensuring that the device is properly terminated. Additionally, use the FDC3535's built-in USB fault detection and correction features to ensure reliable data transfer.
The FDC3535 has built-in ESD protection, but additional protection measures can be taken, such as using ESD protection diodes, following proper handling and storage procedures, and using a shielded enclosure to prevent external ESD events.
