PCM2902BDBR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VAA and VCCO). This ensures that the internal voltage regulators are powered up correctly.
  • To configure the PCM2902BDBR for master mode operation, set the M/S pin high and the BCK pin as the clock output. The device will then generate the clock signal for the audio interface.
  • The maximum clock frequency supported by the PCM2902BDBR is 50 MHz. However, the recommended clock frequency is 12.288 MHz for 44.1 kHz audio sampling rate.
  • The PCM2902BDBR outputs digital audio data in I2S format. The data is output on the DOUT pin, and the clock signal is output on the BCK pin. The data is MSB-first, and the word length is 16 bits or 24 bits, depending on the configuration.
  • The analog power supplies (VAA and VCCO) are used to power the analog-to-digital converter (ADC) and the digital-to-analog converter (DAC) in the PCM2902BDBR. These power supplies should be decoupled from the digital power supply (VCC) to minimize noise and ensure proper operation.
