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.

Digital to analog converting system and digital to analog converting method

A frame timing controller includes a timer, a frame timing control unit, and a frame pointer processing circuit. The timer is arranged to generate a timer value according to a first clock signal with a first clock frequency. The frame timing control unit is for triggering at least a receiver to start receiving transmitted information of a base station according to at least a frame pointer and the timer value, wherein the receiver processes an input signal to generate first samples at a first sampling rate corresponding to a sampling clock frequency and processes the first samples to generate an output signal including second samples at a second sampling rate corresponding to a second clock frequency of a second clock signal different from the sampling clock frequency. The frame pointer processing circuit is for generating and updating the frame pointer according to the output signal of the receiver.
