Abstract

In einer Oszillatorschaltung ist ein wertdiskreter abstimmbarer Oszillator (4) mit einem über eine Schalteinrichtung (5) zuschaltbaren Abstimmglied (6) vorgesehen. Eine mit dem Ausgang (41) des Oszillators (4) verbundene Gleichrichterschaltung (8) bildet aus dem Oszillatorsignal ein Taktsignal. Weiterhin enthält die Oszillatorschaltung eine Phasenverzögerungsschaltung (9) mit einem Schalteingang (91), mit einem Taktsignaleingang (97), der mit dem Ausgang der Gleichrichterschaltung (8) gekoppelt ist, und mit einem Schaltausgang (96), der mit der Schalteinrichtung (5) gekoppelt ist. Die Phasenverzögerungsschaltung (9) weist eine Vergleichsschaltung (94) zum Vergleich einer Phase des am Signaleingang anliegenden Taktsignals mit einer Referenzphase auf. Sie ist zur Abgabe eines Schaltsignals nach Anliegen eines Aktivierungssignals am Schalteingang (91) und nach einer Übereinstimmung der Phase des am Signaleingang (97) anliegenden Taktsignals und der Referenzphase ausgebildet. Dadurch wird der Schaltvorgang so lange verzögert, bis die Sprungantwort des Ausgangssignals des Oszillators keinen Phasensprung im Taktsignal verursacht.
