SPREAD-PERIOD CLOCK GENERATOR |
摘要 |
<p>A spread-period clock generator (SPC) counts basic clock pulses (XK) to generate output pulses (EQ) with varying periods, and has means (controlled by signal QS) for switching between a first mode, in which counting is carried out in response to the leading edges of the basic clock pulses (CK), and a second mode, in which counting is carried out in response to the trailing edges of the basic clock pulses (CK). Accordingly, if mode switching (signal QS) is carried out during a counting operation, the counting period is altered by a portion of a basic clock period (CK). Thus, the number of different periods of the output pulses can be increased without increasing the basic clock frequency (input WC, signal LK, CK).</p> |
