ABSTRACT:
A method for controlling a programmable source of a plurality of string of clock signals, a program is stored with a plurality of different indications of desired frequencies, each indication corresponding to one of the strings of clock signals. The frequency of each of a plurality of oscillator is controlled by the memory content of a separate memory for each oscillator. The content of each memory is adjusted in accordance with the actual frequency of each string, the frequency indicated by the corresponding indication of a desired frequency and a reference.
