PCM1803ADBR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper operation and prevents damage to the device.
  • The analog input filter should be designed to reject noise and interference, while allowing the desired signal to pass through. A 3rd-order Butterworth filter with a cutoff frequency of around 10 kHz is a good starting point. The filter components should be chosen to minimize noise and distortion.
  • The recommended clock frequency for the PCM1803ADBR is 256 fs, where fs is the sampling frequency. This ensures that the device operates within its specified performance parameters.
  • Clock jitter can be minimized by using a high-quality clock source, such as a crystal oscillator, and by ensuring that the clock signal is properly terminated and filtered. The PCM1803ADBR also has a built-in clock jitter attenuator that can be enabled to reduce the effects of clock jitter.
  • The maximum input signal level for the PCM1803ADBR is 2.5 Vrms. Exceeding this level can result in distortion and reduced performance.
