PCM1690IDCARQ1 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the analog and digital components on opposite sides of the board. Also, keep the clock lines short and away from noisy signals.
  • The PCM1690 supports clock frequencies up to 256 fs (12.288 MHz). However, the maximum clock frequency may vary depending on the specific application and system requirements.
  • To configure the PCM1690 for 24-bit audio, set the BOSR pin to logic high, and configure the serial interface to 24-bit mode by setting the appropriate bits in the control register.
  • The recommended decoupling capacitor value is 0.1 μF to 1 μF, depending on the specific application and power supply noise requirements.
