Abstract
Official abstract text for this publication.
A method and an arrangement for generating a clock signal by a phase locked loop in which the time for adjusting to a prescribed frequency and phase of a clock signal is reduced by virtue of the fact that a plurality of selection signals respectively shifted by a time difference delta t are generated from the divided clock signal. A comparison signal (capture) is generated under control by an edge of the reference clock and a comparison is started in the case of which what is selected is that selection signal shifted by delta t which exhibits with its edge the least possible time deviation from the edge of the comparison signal, and the selected selection signal is output.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for generating a clock signal by a phase locked loop, in which a divided clock signal generated from the clock signal is compared with a reference clock, and a frequency and a phase angle of the clock signal to be generated is set as a function of said comparison, comprising: generating a plurality of delayed divided clock signals respectively shifted by a time difference delta t from the divided clock signal, generating a capture signal under…
