CS4362-KQZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS4362-KQZ?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I configure the CS4362-KQZ for master clock mode?
  To configure the CS4362-KQZ for master clock mode, set the MCLK pin to the desired clock frequency, and ensure that the BCLK pin is tied to the MCLK pin. Additionally, set the I2S format to 'Master' mode through the I2C interface.
• What is the maximum allowed capacitance for the analog output filters?
  The maximum allowed capacitance for the analog output filters is 10nF. Exceeding this value may affect the device's performance and stability.
• How do I optimize the CS4362-KQZ for low power consumption?
  To optimize the CS4362-KQZ for low power consumption, use the Power Down mode (PD pin low), reduce the clock frequency, and minimize the analog output voltage swing. Additionally, consider using the device's built-in power-saving features, such as the Auto-Power Down mode.
• What is the recommended layout and routing for the CS4362-KQZ?
  The recommended layout and routing for the CS4362-KQZ involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, ensure that the power supply decoupling capacitors are placed close to the device.
