Provided is a system and method for converting digital data audio data audio
data that has a predetermined input sample rate, into an analog data signal. A
system includes a digital to analog converter (DAC) including a digital processing
portion configured to receive as an input the digital audio data and timing information,
the timing information being representative of a time base of the input sample
rate. The digital processing portion is similarly configured to digitally process
the digital audio data and the timing information to produce serialized output
data. The DAC also includes an analog processing portion configured to convert
serialized data to an analog format. The digital processing portion operates in
accordance with at least one clock having a corresponding clock rate wherein the
corresponding clock rate is unrelated to the input sample rate.
