CS42438-DMZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply analog power (AVDD) first, followed by digital power (DVDD), and then bring the reset pin (RST) high.
  • To configure the CS42438-DMZ for master clock mode, set the MCLK pin as an output by setting the MCLKOE bit in the Clock Control Register (0x10). Then, set the desired clock frequency using the MCLKDIV registers (0x11-0x12).
  • The maximum allowed capacitance for the analog input filters is 10nF. Exceeding this value may affect the device's performance and stability.
  • To optimize the CS42438-DMZ for low power consumption, disable unused features and interfaces, reduce the clock frequency, and use the power-down modes (e.g., ADC power-down, DAC power-down) when not in use.
  • The recommended layout and routing for the CS42438-DMZ involves separating analog and digital signals, using a solid ground plane, and minimizing signal trace lengths and vias. Refer to the Cirrus Logic application note AN215 for more detailed guidelines.
