AD9238BSTZ-65 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog and digital power plane is recommended. Keep the analog and digital signals separate and avoid crossing them over each other. Use a common mode filter and a ferrite bead to filter the power supply.
  • Use a low-jitter clock source (<100 ps) and ensure the clock signal is properly terminated. Use a clock signal with a frequency that is an integer multiple of the sampling frequency to minimize jitter. Also, ensure the clock signal is not over-driven or under-driven.
  • Power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures that the analog circuitry is powered up before the digital circuitry.
  • The AD9238BSTZ-65 outputs 16-bit data in a CMOS-compatible format. Use a FIFO or a buffer to handle the output data, and ensure the receiving device can handle the data rate of up to 65 MSPS.
  • The AD9238BSTZ-65 has a maximum junction temperature of 150°C. Ensure good airflow around the device, and use a heat sink or a thermal pad to dissipate heat. Avoid blocking the airflow around the device.
