PCM1780DBQ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VAA and VDA). This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the analog output stage, ensure that the output filter components (Rf and Cf) are properly selected to match the load impedance and desired frequency response. Additionally, use a low-ESR capacitor for the output coupling capacitor (Cc) to minimize distortion.
  • The recommended clocking scheme is to use a single clock source for both the digital and analog sections. This ensures that the digital and analog circuits are synchronized, reducing jitter and improving overall performance.
  • The PCM1780DBQ outputs data in a 24-bit, MSB-first, left-justified format. Ensure that the receiving device is configured to accept this format to avoid data corruption or misinterpretation.
  • The internal voltage regulators (VREG1 and VREG2) provide regulated power supplies for the analog and digital sections, respectively. These regulators can be used to power external circuitry, but ensure that the total current drawn does not exceed the recommended maximum current rating.
