The recommended layout and routing for the WM8904CGEFL/V can be found in the Cirrus Logic application note AN235, which provides guidelines for PCB layout, component placement, and routing to ensure optimal performance and minimize noise.
The WM8904CGEFL/V can be configured for different audio interfaces such as I2S, SPI, and AC'97 through the use of registers and control pins. The specific configuration will depend on the application and the interface required. Refer to the datasheet and application notes for more information.
The power consumption of the WM8904CGEFL/V depends on the operating mode and the clock frequency. In typical audio playback mode, the power consumption is around 20-30mA. In standby mode, the power consumption is around 1-2mA. Refer to the datasheet for more information on power consumption in different operating modes.
The WM8904CGEFL/V has a mute pin that can be used to mute the audio output. The mute pin can be controlled through a digital signal or a GPIO pin. When the mute pin is asserted, the audio output is muted. Refer to the datasheet for more information on the mute function.
The WM8904CGEFL/V can operate with a clock frequency range of 10MHz to 50MHz. The recommended clock frequency is 12.288MHz or 24.576MHz for most audio applications.
