The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures that the internal voltage regulators and clock circuitry are properly initialized.
-
To configure the WM8753 for master clock mode, set the MCLK pin as an output by writing to the Clock Control Register (CKCNTRL). Then, set the desired clock frequency using the Master Clock Frequency Register (MCLKFREQ).
-
The maximum input voltage for the ADC is VDDIO + 0.3V. Exceeding this voltage may cause damage to the device or affect its performance.
-
To optimize power consumption, use the Power Management Register (PWRCNTRL) to disable unused blocks and features. Additionally, adjust the clock frequency and voltage supply to the minimum required for the application.
-
Keep analog and digital signals separate, and use a star-ground configuration to minimize noise and interference. Use short, direct traces for clock and data signals, and avoid crossing analog and digital signals.
