The recommended power-up sequence is to apply analog power (AVDD) first, followed by digital power (DVDD), and then bring the reset pin (RST) high.
To configure the CS4245-CQZ for master clock mode, set the MCLK pin as an output by setting the MCLKOE bit in the Clock Control Register (0x10). Then, set the desired clock frequency using the MCLKDIV bits in the Clock Control Register.
The maximum allowed capacitance for the analog input filters is 10nF. Exceeding this value may affect the device's performance and stability.
To optimize the CS4245-CQZ for low power consumption, disable any unused features, reduce the clock frequency, and use the power-down modes (e.g., ADC power-down, DAC power-down) when not in use.
The recommended layout and routing for the CS4245-CQZ involves separating analog and digital signals, using a solid ground plane, and minimizing signal trace lengths and loops to reduce noise and interference.
