PCM1861QDBTRQ1 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is stable before the digital circuitry is powered up.
  • To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signal traces separate. Also, place the decoupling capacitors close to the device pins and use a low-impedance path for the power supply lines.
  • The maximum clock frequency that can be used with the PCM1861QDBTRQ1 is 50 MHz. However, the actual clock frequency used may be limited by the specific application and the quality of the clock signal.
  • The PCM1861QDBTRQ1 can be configured for different audio formats using the control registers. For example, to configure the device for 16-bit, 48 kHz audio, set the register bits accordingly. Refer to the datasheet for the specific register settings for different audio formats.
  • The recommended operating temperature range for the PCM1861QDBTRQ1 is -40°C to 85°C. However, the device can operate up to 105°C with reduced performance and reliability.
