WM8950CGEFL/RV datasheet by Cirrus Logic

WM8950CGEFL/RV Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the WM8950?
  The recommended power-up sequence is to apply VDDIO, followed by VDDD, and then VDDA. This ensures that the internal voltage regulators are powered up in the correct order.
• How do I configure the WM8950 for a specific audio interface?
  The WM8950 can be configured for different audio interfaces (e.g. I2S, SPI, etc.) using the device's control registers. Refer to the datasheet for specific register settings and configuration options.
• What is the maximum clock frequency supported by the WM8950?
  The WM8950 supports clock frequencies up to 50 MHz. However, the maximum clock frequency may vary depending on the specific application and system design.
• How do I optimize the WM8950's power consumption for low-power applications?
  To optimize power consumption, use the WM8950's power-down modes, adjust the clock frequency, and optimize the system's voltage supply. Additionally, consider using the device's dynamic voltage and frequency scaling (DVFS) feature.
• What is the WM8950's latency for audio data transmission?
  The WM8950's latency for audio data transmission is typically in the range of 1-2 milliseconds, depending on the specific audio interface and system configuration.
