ABSTRACT:
Data signals which vary between first and second levels are applied to an operational amplifier by a timing signal produced in response to data signal transitions. The operational amplifier is connected to produce a nominal voltage in the absence of data signals, and to produce first and second voltages above and below the nominal voltage by equal amounts in response to the first and second data levels. The voltages so produced are used to control the frequency of an oscillator.
