PCM1808QPWRQ1 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 analog input circuitry, use a low-pass filter to remove high-frequency noise, and ensure that the input impedance is matched to the source impedance. Also, use a high-quality, low-noise analog power supply.
  • The maximum clock frequency that can be used with the PCM1808 is 256 fs (where fs is the sampling frequency). For example, at a sampling frequency of 44.1 kHz, the maximum clock frequency would be 11.2896 MHz.
  • The PCM1808 outputs data in a 24-bit, MSB-first, left-justified format. The data is output on the DOUT pin, and the clock signal is output on the BCK pin. The data is valid on the rising edge of the BCK signal.
  • The MUTE pin is used to mute the analog input signal. When the MUTE pin is high, the analog input signal is disconnected from the ADC, and the output data is set to zero.
