PCM4220PFBR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by AVDD, and then DVDD. This ensures that the internal voltage regulators are powered up correctly.
  • The analog input filter should be optimized for the specific application. A good starting point is to use a 3rd-order Butterworth filter with a cutoff frequency of 10-20 kHz. The filter should be designed to reject noise and aliasing, while allowing the signal of interest to pass through.
  • The maximum clock frequency that can be used with the PCM4220 is 128 MHz. However, the actual clock frequency used may be limited by the specific application and the quality of the clock signal.
  • The digital output data from the PCM4220 is in 2's complement format. The data should be processed and formatted according to the specific requirements of the application. This may include data alignment, byte swapping, and formatting for transmission or storage.
  • The recommended layout and routing for the PCM4220 involves separating the analog and digital sections of the board, using a solid ground plane, and minimizing noise and interference. The analog input traces should be short and direct, and the digital output traces should be routed away from the analog section.
