摘要:the synchronisierungseinrichtung serves to generate a synchronized pulsesequence with the help of an internal ar\beitstaktes (sy ck) from an external digitalsignal\impulsfolge (data) on the arbeitstaktes equal frequency, but indeterminatephase with the help of two serial placed or flip flops (ffl ff2).one is in time to thesignalimpulsfolge the respective signalzustand buffered. the other flipflop is thusprepared and is caused by the internal arbeitstakt, the synchronized pulse sequence.theeinsynchronisieren (fangzustand) is a schaltstufe (ff4), by the signalimpulsfolge assignedbeat (wr ck) in a first condition, and a corresponding output signal gesteu\ert (b)ab\gibt.in a frequenzteiler (ff5), by the aus\gangssignal (b) of the schaltstufe(ff4) triggered a in\ternes clock signal (int ck) compared to the arbeitstakt n timesthe frequency in the ratio l \\/ n stocky and as arbeitstakt a synchronized clock signal (syck) er\zeugt with au ch the schaltstufe (ff4) in a second state is toggled.in thenormal betriebszu\stand (synchronbetrieb) is the schaltstufe (ff4)deakti\viert and frequenzteiler (ff5) is continuous.
