The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
To configure the PCM4104 for master clock mode, set the MCLK pin to the desired clock frequency, and set the MCLKDIV pin to the appropriate division ratio. Also, ensure that the BCLK and LRCLK pins are not connected to an external clock source.
The maximum input voltage for the ADC inputs is VCC - 0.5V. Exceeding this voltage may cause damage to the device.
To optimize the PCB layout, keep the analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the power pins. Also, ensure that the clock signals are routed away from the analog signals.
The recommended operating temperature range for the PCM4104 is -40°C to 85°C. Operating the device outside this range may affect its performance and reliability.
