Abstract: A digital to analog converting system, which comprises: a first data converting circuit, for receiving a first digital data stream transmitted at a first clock frequency, for converting the first digital data stream to a plurality of second digital data streams transmitted at a second clock frequency, and for outputting the second digital data streams in parallel; a second data converting circuit, for receiving the second digital data streams from the first data converting circuit, and for converting the second digital data streams to a third digital data stream transmitted at a third clock frequency; and a first digital to analog converter, for converting the third digital data stream to a first output analog data stream. The second clock frequency is lower than the first clock frequency and the third clock frequency.
