The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog inputs. This ensures that the internal voltage regulators are powered up correctly.
To minimize noise and ensure optimal performance, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signal traces separate and away from each other.
The PCM4104 supports clock frequencies up to 50 MHz, but the maximum frequency may vary depending on the specific application and system requirements.
The PCM4104 can be configured for differential or single-ended analog input by setting the appropriate bits in the control register. For differential input, set the DIFF bit to 1, and for single-ended input, set it to 0.
The recommended decoupling capacitor value is 0.1 μF to 1 μF, depending on the specific application and system requirements. A larger capacitor value may be required for high-frequency applications.
