PCM1804DBRG4 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
  • Use a low-pass filter with a cutoff frequency below 20 kHz to remove high-frequency noise, and ensure the input impedance is matched to the analog source. Also, use a buffer amplifier if the source impedance is high.
  • The maximum allowed clock jitter is 100 ps RMS. Exceeding this value can result in increased jitter in the digital output signal.
  • Yes, but ensure that the analog ground plane is connected to the digital ground plane at a single point, preferably near the power supply. This helps to reduce noise and improve performance.
  • The PCM1804 outputs data in I²S format. Ensure that the receiving device is configured to accept I²S data, and that the clock and data lines are properly synchronized.
