PCM2705DBR Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
  • To configure the PCM2705DBR for master mode operation, set the MCLK pin as the clock source, and connect the BCLK and WCLK pins to the corresponding clock signals. Additionally, set the MS bit in the control register to '1' to enable master mode.
  • The maximum allowed capacitance on the VCC and VDD pins is 10uF. Exceeding this value may cause power-on reset issues or affect the device's performance.
  • The PCM2705DBR's digital output data format is in I2S (Inter-IC Sound) format. The device outputs 24-bit or 16-bit data, depending on the configuration, with the MSB (Most Significant Bit) first. The data is transmitted on the DOUT pin, and the clock signal is provided on the BCLK pin.
  • The XF pin is an external filter pin that allows the user to connect an external filter capacitor to improve the device's jitter tolerance. Connect a 10nF to 100nF capacitor between the XF pin and ground to improve the device's performance.
