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 PCM1771PWR for master clock mode, set the MCLK pin to the desired clock frequency, and set the M/S pin to logic high. Also, ensure that the BCK pin is connected to the clock output of the master device.
The maximum allowed capacitance for the AVCC and DVCC decoupling capacitors is 10uF. Exceeding this value may affect the stability of the internal voltage regulators.
To optimize the PCB layout for the PCM1771PWR, ensure that the analog and digital power supplies are separated, and that the analog signals are routed away from the digital signals. Also, use a solid ground plane and decouple the power supplies with 0.1uF capacitors.
The recommended operating temperature range for the PCM1771PWR is -40°C to 85°C. Operating the device outside this range may affect its performance and reliability.
