ABSTRACT:
The present invention addresses the generation of a controlled clock source for use in trimming VCDL delay line output clocks. In this trimming process, adjustments are made for static variations in these output clocks. The invention's use of a controlled clock source eliminates the need for this trimming process to be conducted in real time and reduces the expense of the circuitry required.
