The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and the device is properly initialized.
To configure the PCM1772RGAR for master clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and configure the serial data format using the SDIF pin.
The maximum allowed capacitance on the VCC and VDD pins is 10uF. Exceeding this value may cause power-up issues or affect the device's performance.
To optimize the PCB layout for the PCM1772RGAR, keep the analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the VCC and VDD pins. Also, ensure that the clock signals are routed away from the analog signals to minimize noise coupling.
The recommended operating temperature range for the PCM1772RGAR is -40°C to 85°C. Operating the device outside this range may affect its performance or reliability.
