PCM2704DB Frequently Asked Questions (FAQs)

  • The recommended clock source for the PCM2704DB is a crystal oscillator or a high-quality clock source with low jitter. The clock frequency should be 12.288 MHz or 24.576 MHz for 44.1 kHz or 48 kHz sampling rates, respectively.
  • To configure the PCM2704DB for master mode operation, set the MCLK pin as the clock output and connect it to the external clock source. Set the BCLK pin as the bit clock output and connect it to the external codec or DAC. Set the WCLK pin as the word clock output and connect it to the external codec or DAC. Finally, set the MODE pin to logic high to enable master mode.
  • The maximum data transfer rate of the PCM2704DB is 24 bits at 96 kHz, which translates to a data transfer rate of 2.304 Mbps.
  • The PCM2704DB uses a 5th-order Bessel filter for digital filtering. The filter coefficients are stored in the device's internal ROM and can be accessed through the I2C interface. The coefficients can be modified or updated using the I2C interface, but it is not recommended to modify the default coefficients without proper understanding of the filter design and its impact on the audio performance.
  • The power consumption of the PCM2704DB depends on the operating mode and the clock frequency. In typical operating conditions, the power consumption is around 20-30 mA at 3.3V supply voltage. However, the power consumption can be reduced to around 10-15 mA in low-power mode.
