PX1011B-EL1/G,551 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
• How do I ensure electromagnetic compatibility (EMC) compliance?
  Follow the recommended PCB layout, use a metal shield around the device, and ensure proper grounding and decoupling. Additionally, use a common mode choke and TVS diodes for ESD protection.
• What is the recommended power-up sequence for the device?
  Power up the device in the following sequence: VDD, AVDD, and then DVDD. Ensure that the power supplies are stable and within the recommended voltage range before applying the input signals.
• How do I handle thermal management for the device?
  Use a thermal pad or a heat sink to dissipate heat. Ensure good airflow around the device, and avoid blocking the thermal pad or heat sink. Monitor the device temperature and adjust the thermal management strategy accordingly.
• What are the recommended input signal levels and termination?
  The recommended input signal levels are 0.5V to 2.5V. Use a 50-ohm termination resistor in series with the input signal, and a 50-ohm load resistor to ground.
