Abstract

An electronic chip has a data input for receiving an input digital data signal with a data frequency, a plurality of switches, and a logic circuit operatively coupled with both the plurality of switches and the data input. The logic circuit controls the switches to be in one of a DAC mode or a mixer mode. The DAC mode causes the switches to convert the input digital data signal into a DAC analog signal having about the data frequency. The mixer mode, however, causes the switches to convert the input digital data signal into a mixed analog signal having a mixer frequency that is higher than the data frequency.
