WM8805GEDS/V Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a star-configuration for the power supply. Refer to the Cirrus Logic application note AN215 for more details.
  • To configure the WM8805GEDS/V for Master Clock Mode, set the MCLK pin to the desired clock frequency, and set the MCLKDIV pin to the appropriate division ratio. Ensure that the clock source is stable and meets the specified jitter requirements.
  • The recommended power-up sequence is: 1) Power up the analog supply (AVDD), 2) Power up the digital supply (DVDD), and 3) Apply the clock signal. Ensure that the power supplies are stable before applying the clock signal.
  • Use a logic analyzer to verify the I2S clock and data signals. Check the I2S configuration registers to ensure that the correct format and sample rate are set. Verify that the I2S clock is stable and within the specified frequency range.
  • The maximum cable length supported by the WM8805GEDS/V's S/PDIF interface is approximately 10 meters (33 feet) using a high-quality, shielded coaxial cable.
