Abstract:
A data conversion integrated circuit for receiving a signal in the time domain and providing an output in the frequency domain, comprising:a data converter formed on an integrated circuit substrate for converting data from an analog format in the time domain to a digital format in the time domain to provide an output at a predetermined data width with a corresponding number of data lines; a transform processor formed on said integrated circuit substrate for processing the data in the digital format output through a time domain/frequency domain transform to provide data in a digital format in the frequency domain to provide an output at a predetermined data width with a corresponding number of data lines; an interface formed on said integrated circuit substrate for interfacing the output of said data converter with its associated predetermined data width to the input of said transform processor; and an output interface from the integrated circuit for providing an output of at least the output of said transform processor, said output interface having less data lines than the output of said transform processor, wherein the output of said data converter and the output of said transform processor are input to a multiplexer, said multiplexer controlled by a control signal to select either the output of said data converter or the output of said transform processor to provide a single output from the data conversion circuit to said output interface.
