The recommended power-up sequence is to apply VDD first, followed by VCC, and then the analog power supplies (AVDD and DVDD). This ensures proper device operation and prevents latch-up.
To configure the CS4334-DSZR for master clock mode, set the MCLK pin to the desired clock frequency, and ensure that the MCLKDIV pin is tied to VDD. Additionally, set the BCK pin to the desired bit clock frequency, and configure the WS pin to generate the word clock signal.
To minimize noise and ensure proper device operation, it is recommended to separate the analog and digital power supplies, and use separate power planes and decoupling capacitors for each. Additionally, keep the analog and digital signal traces separate and avoid crossing them over each other.
To optimize the CS4334-DSZR's performance for low power consumption, use the device's power-down modes, reduce the clock frequency, and minimize the analog and digital signal activity. Additionally, consider using a lower voltage supply and optimizing the device's configuration for the specific application.
To mitigate EMI and RFI when using the CS4334-DSZR, use proper shielding, grounding, and filtering techniques. Ensure that the device is placed in a shielded enclosure, and use ferrite beads or chokes to filter the power supplies. Additionally, minimize the length of the analog and digital signal traces, and use differential signaling where possible.
