ABSTRACT:
In an exemplary embodiment, a multi-rate data conversion circuit receives digital data at varying data rates, receives a data rate input corresponding to the digital data and converts the digital data to a converted output based upon the data rate input. A direct digital synthesis circuit receives the converted output and synthesizes a modulated output signal based upon the converted output. A multi-rate converter receives the digital data, the data rate input and a clock signal and converts the digital data to converted digital data. A multi-rate digital data filter receives the converted digital data and produces a filtered digital output. An output scaler receives the filtered digital output and produces a scaled and filtered digital output. Finally, an adder combines the scaled and filtered digital output with a center frequency input and produces the converted output.
