We are using a small CPLD to bridge between the SSP serial port and a CS4431 stereo dac. We have an I2C silicon oscillator being used so we can set any sample rate we want. Currently, its working at 22.05KHz. We haven't change the sample rate yet. I want to be able to run 8Khz to 48KHz MP3s. Is there anything in the mad decoder that would prevent decoding MP3s within this range? We don't have a sample issue with our hardware since we can set any sample rate we want.
