The recommended layout and placement for the WM8940CGEFL/RV can be found in the Wolfson Microelectronics application note AN124, which provides guidelines for PCB layout, component placement, and thermal management to ensure optimal performance and minimize noise and interference.
The WM8940CGEFL/RV can be configured for different audio interfaces such as I2S, SPI, and AC'97 through the use of external resistors and capacitors, as well as programming the device's registers. The datasheet provides a detailed description of the configuration options and the required external components.
The power consumption of the WM8940CGEFL/RV varies depending on the operating mode. In idle mode, the device consumes around 10mA, while in active mode, it consumes around 30mA. The power consumption can be further reduced by using the device's power-down modes and dynamic voltage scaling. The datasheet provides a detailed power consumption table for different operating modes.
The WM8940CGEFL/RV has built-in noise reduction and echo cancellation algorithms that can be enabled through the device's registers. The datasheet provides a detailed description of the algorithms and the required programming to enable them. Additionally, Wolfson Microelectronics provides software development kits (SDKs) and application notes that provide example code and guidelines for implementing noise reduction and echo cancellation.
The WM8940CGEFL/RV supports clock frequencies up to 50MHz, but the recommended clock frequency is 12.288MHz or 24.576MHz for optimal performance and power consumption.
