ADS5403IZAY Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the ADS5403IZAY?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital signals separate, and use a common mode filter to reduce noise.
• How do I optimize the clock input for the ADS5403IZAY?
  Use a low-jitter clock source, and ensure the clock signal is properly terminated. A clock frequency of 1.2 GHz or higher is recommended for optimal performance.
• What is the recommended power-up sequence for the ADS5403IZAY?
  Power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock input. Ensure all supplies are stable before applying the clock signal.
• How do I handle the thermal management of the ADS5403IZAY?
  Use a heat sink or thermal pad to dissipate heat. Ensure good airflow around the device, and avoid blocking the thermal pads on the package.
• What is the recommended input signal conditioning for the ADS5403IZAY?
  Use a low-pass filter or a band-pass filter to condition the input signal, and ensure the signal is within the recommended amplitude range (typically 1 Vpp).
