The recommended power-up sequence is to apply VDD first, followed by AVDD, and then DVDD. This ensures that the internal voltage regulators are powered up in the correct order.
To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the analog and digital components on opposite sides of the board. Also, keep the clock and data lines as short as possible and away from noise sources.
The PCM1863 supports clock frequencies up to 50 MHz, but the maximum frequency may vary depending on the specific application and system requirements.
The PCM1863 can be configured for master or slave mode by setting the appropriate bits in the control register. In master mode, the PCM1863 generates the clock signal, while in slave mode, it receives the clock signal from an external source.
The recommended decoupling capacitor value is 0.1 μF to 1 μF, depending on the specific application and system requirements. The capacitor should be placed as close as possible to the power pins.
