PCM2904DBR 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.
  • To configure the PCM2904DBR for master mode operation, set the M/S pin high, and ensure that the BCK pin is driven by the internal clock generator or an external clock source.
  • The maximum clock frequency supported by the PCM2904DBR is 50 MHz. However, the recommended clock frequency is 12.288 MHz for 44.1 kHz audio sampling rate.
  • The PCM2904DBR outputs data in I2S format. The device can be configured to output data in either MSB-first or LSB-first format, depending on the setting of the DFS pin.
  • The VREF pin is used to set the analog reference voltage for the ADC and DAC converters. It should be connected to a stable voltage source, typically 2.5V or 3.3V, depending on the application.
