Abstract
A data conversion system and method are described. A first phase locked loop includes a controllable frequency oscillator circuit to receive a digital data stream and output a reference frequency signal, and includes an oscillator and at least one variable load connected to the oscillator which is controllable to tune the oscillator frequency and vary the frequency of the reference frequency signal. A second phase locked loop includes a divide by N function in a feedback loop (where N has an integer value), and receives the reference frequency signal and outputs a recovered clock signal corresponding to an original clock signal associated with the digital data stream. The recovered clock signal is used to clock a data converter to convert the digital data into an analog output signal.
