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 CS4335-KSZ for master clock mode, set the MCLK pin as the clock source, and ensure that the MCLK frequency is within the recommended range of 10-50 MHz. Additionally, set the BCLK pin to the desired bit clock frequency.
The SYNC pin is used to synchronize the CS4335-KSZ with an external clock source. To use it, connect the SYNC pin to the external clock source, and ensure that the clock frequency is within the recommended range. This allows the CS4335-KSZ to synchronize its internal clock with the external clock source.
To optimize the CS4335-KSZ for low power consumption, use the power-down modes (PD0-PD3) to disable unused blocks, reduce the clock frequency, and minimize the voltage supply. Additionally, consider using the dynamic voltage and frequency scaling (DVFS) feature to optimize power consumption based on the system's requirements.
The recommended layout and routing for the CS4335-KSZ involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock and data lines. Additionally, ensure that the power supply lines are decoupled and filtered to reduce noise and interference.
