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 PCM1789PW for master clock mode, set the MCLK pin to the desired clock frequency, and set the M/S pin to logic high. Then, set the BCK pin to the desired bit clock frequency, and set the LRCK pin to the desired word clock frequency.
The maximum allowed capacitance for the analog input filters is 10nF. Exceeding this value may affect the performance of the ADC.
To optimize the PCB layout, keep the analog and digital grounds separate, and use a solid ground plane for the analog section. Keep the analog input traces short and away from digital signals, and use a low-ESR capacitor for the AVCC pin.
The recommended operating temperature range for the PCM1789PW is -40°C to 85°C. Operating outside this range may affect the performance and reliability of the device.
