PCM1781DBQ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures that the internal voltage regulators are powered up correctly and the device is properly initialized.
  • To configure the PCM1781DBQ for master clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. The device will then generate the LRCK signal internally.
  • The maximum allowed jitter on the clock input is 500 ps. Exceeding this limit may result in errors or unstable operation.
  • Yes, the PCM1781DBQ can be used with a separate analog power supply. However, it is recommended to use a low-noise, low-ripple power supply to ensure optimal performance.
  • To optimize the PCB layout for the PCM1781DBQ, keep the analog and digital signal traces separate, use a solid ground plane, and minimize the length of the clock signal traces. Also, ensure that the power supply decoupling capacitors are placed close to the device.
