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 CS42L51-DNZ for master clock mode, set the MCLK pin as the clock source, and ensure that the MCLK frequency is within the specified range (10-50 MHz). Also, set the BCLK pin as the bit clock output, and configure the LRCLK pin as the frame clock output.
The maximum allowed capacitance for the analog output filters is 10uF. Exceeding this value may affect the device's stability and performance.
To optimize the CS42L51-DNZ for low power consumption, use the power-down modes (e.g., PDN, PDNI) when not in use, reduce the clock frequency, and minimize the analog output load capacitance. Additionally, consider using the device's built-in power-saving features, such as the automatic power-down mode.
For optimal performance, keep the analog and digital signal paths separate, use a solid ground plane, and minimize the length of the analog output traces. Also, ensure that the power supply decoupling capacitors are placed close to the device's power pins.
