CS4392-KZZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS4392-KZZ?
  The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I configure the CS4392-KZZ for master clock mode?
  To configure the CS4392-KZZ for master clock mode, set the MCLK pin as the clock source, and ensure that the MCLK frequency is within the specified range (256 fs to 512 fs). Also, set the BCLK pin to the desired frequency and configure the LRCLK pin accordingly.
• What is the maximum allowed capacitance for the analog output filters?
  The maximum allowed capacitance for the analog output filters is 10 nF. Exceeding this value may affect the device's performance and stability.
• How do I optimize the CS4392-KZZ for low power consumption?
  To optimize the CS4392-KZZ for low power consumption, use the power-down modes (e.g., PDN pin), reduce the clock frequency, and minimize the analog output load. Additionally, consider using the device's built-in power-saving features, such as the automatic power-down mode.
• What is the recommended layout and routing for the CS4392-KZZ?
  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 lines are decoupled and filtered properly.
