Question about sample rate of audio codec WM8731 on DE2. hi, everyone. I have read code from the DE2 I2Sound Demonstration and compared with WM7831 datasheet. Everything is quite clear, except the setting of sample rate. According to the datasheet, when using sample rate of 48 khz, mclk frequency is required to be 12.288 mhz. http ...

DDS running at audio clock rate is connected to the audio codec DAC channels. Code. Quartus Archive. The output frequency is set as F = (SW*(2^14))*(audio clock rate)/(2^32) = SW*(audio clock rate)*(2^-18) = SW*46000*(2^-18) The 2^14 is an scale factor to put the frequency into the audio range. The 2^32 results from using a 32 bit accumulator.
Audio Controller

The audio controller provides a simple interface to the Audio CODEC chip present on the DE2 board. The controller handles the data transmission to and from the chip. The chip configuration is handled by the separate configuration module. The configuration module must be instantiated separately when using the audio controller.
