PCM2904DBG4 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 PCM2904 for master mode operation, set the M/S pin high and ensure that the BCK pin is driven by the PCM2904. The device will then generate the clock signal for the codec.
  • The maximum clock frequency supported by the PCM2904 is 50 MHz. However, the actual clock frequency used depends on the specific application and the requirements of the codec.
  • The FIFO overflow and underflow interrupts can be handled by reading or writing data to the FIFO buffer, respectively, within the specified time frame. The interrupts can be cleared by writing to the interrupt status register.
  • The VREF pin is used to set the reference voltage for the analog-to-digital converter (ADC) and digital-to-analog converter (DAC) in the PCM2904. The recommended voltage range for VREF is 2.4 V to 2.7 V.
