CS43198-CNZR - Cirrus Logic

CS43198-CNZR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS43198-CNZR?
  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.
• How do I optimize the CS43198-CNZR's analog performance?
  To optimize analog performance, ensure proper PCB layout, use a low-ESR capacitor for the AVDD pin, and keep the analog and digital grounds separate. Additionally, use a high-quality, low-jitter clock source and ensure the device is operated within the recommended temperature range.
• What is the maximum allowed capacitance for the analog output filters?
  The maximum allowed capacitance for the analog output filters is 10uF. Exceeding this value may compromise the device's stability and performance.
• How do I configure the CS43198-CNZR for Master Clock Mode?
  To configure the CS43198-CNZR for Master Clock Mode, set the MCLK pin as the clock source, and ensure the MCLK frequency is within the recommended range (10-50 MHz). Additionally, set the appropriate clock divider ratio using the Clock Control Register (0x04).
• What is the recommended method for resetting the CS43198-CNZR?
  The recommended method for resetting the CS43198-CNZR is to assert the RESET pin low for at least 10 clock cycles. This ensures a complete reset of the device and prevents potential issues during power-up.
