AD9681BBCZ-125 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep analog and digital signals separate, and use shielding and filtering to minimize noise. Refer to the AD9681BBCZ-125 evaluation board layout as a reference.
  • Use a low-jitter clock source (<100 ps) and ensure the clock signal is properly terminated. Use a clock frequency that is a multiple of the ADC sampling frequency to minimize jitter. Also, use a clock signal with a 50% duty cycle to ensure proper ADC operation.
  • Power up the analog supply (AVDD) first, followed by the digital supply (DVDD). Ensure that the analog supply is stable before applying the digital supply. Also, ensure that the clock signal is stable before applying the analog input signal.
  • Perform a full-scale calibration after power-up to ensure optimal performance. The calibration process involves applying a full-scale input signal and adjusting the ADC's internal calibration registers. Refer to the AD9681BBCZ-125 datasheet for detailed calibration procedures.
  • The maximum input signal amplitude is 2 Vpp differential. Exceeding this amplitude may result in distortion and reduced ADC performance. Ensure that the input signal is properly attenuated or amplified to stay within the recommended amplitude range.
