Audio

There is a piece WM8978 onboard, which is a stereo multimedia digital signal

codec with speaker driver. The WM8978 is a low power, high quality stereo

multimedia digital signal codec. It is mainly used in portable applications such as

digital cameras and portable digital camcorders. It combines stereo differential

microphone preamplifiers with speakers, headphones and differential, stereo line

output drivers to reduce the external components necessary for the application,

such as advanced on-chip digital signal processing function with separate

microphone or headphone amplifiers, including a 5-band equaliser, a mixed signal

Automatic Level Control for the microphone or line input through the ADC as well

as a purely digital limiter function for record or playback. The WM8978 digital

audio interface can operate as a master or a slave. An internal PLL can generate all

required audio clocks for the CODEC from common reference clock frequencies.

The design schematic is as follows
