You could just divide by 2 (giving 25MHz). This would result in a sampling rate slightly more than 48KHz, but depending on your application would probably not make an audible difference. --- Quote End --- Dear sir i have done the intitialization of the codec registor by using the 50Mhz crystal i am getting ack , sir i am not getting whether xclk i.e the master clock of codec must require to fetch the data from LR chanal please sugest the logic for sound fetching & more about the DSP mode of codec.
