PCM1793DB Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the analog and digital circuits are powered up in the correct order.
  • To minimize noise and ensure optimal performance, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signal traces separate and away from each other.
  • The maximum clock frequency that can be used with the PCM1793DB is 128 fs (where fs is the sampling frequency). For example, for a sampling frequency of 44.1 kHz, the maximum clock frequency would be 5.6448 MHz.
  • The digital filter coefficients for the PCM1793DB are stored in the device's internal ROM. However, the coefficients can be overridden by loading custom coefficients into the device's registers. The coefficients should be scaled to ensure that the maximum value is within the range of the 24-bit register.
  • The recommended operating temperature range for the PCM1793DB is -40°C to 85°C. However, the device can operate up to 125°C with reduced performance and reliability.
