The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper device initialization and prevents potential latch-up conditions.
To configure the CS43198-CWZR for master clock mode, set the MCLK pin as the clock source, and ensure that the MCLK frequency is within the specified range (e.g., 256 fs, 384 fs, or 512 fs). Additionally, set the BCLK and LRCLK pins accordingly, and configure the device registers to select the desired clock mode.
The maximum allowed capacitance for the analog output filters is 10 nF. Exceeding this value may affect the device's performance and stability.
To optimize power consumption, ensure that the device is operated within the recommended voltage range, and consider using the device's power-down modes (e.g., D1, D2, or D3) when not in use. Additionally, optimize the clock frequency and configure the device registers to minimize power consumption.
To minimize noise and ensure optimal performance, separate the analog and digital signal traces, and use a ground plane to shield the analog signals. Keep the analog signal traces short and away from digital signal traces, and use a common ground point for the analog and digital grounds.
