PCM2704CDB Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VAA and VDA). This ensures that the internal voltage regulators are powered up correctly.
  • To configure the PCM2704CDB for master mode operation, set the MCLK pin to the desired clock frequency, and then set the BCK pin to the desired bit clock frequency. The WS pin should be set to the desired word select frequency. The PCM2704CDB will then generate the necessary clocks and control signals for the DAC.
  • The maximum allowed capacitance on the analog output pins is 100nF. Exceeding this value may affect the stability of the output stage and cause oscillations.
  • The PCM2704CDB outputs data in I2S format by default. To change the output format, use the FMT pin to select between I2S, DSP, or Right-Justified formats. The data format can also be changed through the SPI interface.
  • To minimize noise and ensure proper operation, it is recommended to keep the analog and digital power supplies separate, use a solid ground plane, and keep the signal traces short and away from noise sources. Additionally, use a common mode filter on the analog output pins to reduce EMI.
