Method and circuitry for supplying one of two clock signals to a clock line in dependence on the level of one of both clock signals

摘要

in a oberflu00e4chenwellenfiltertechnik based taktregenerator reclaimed and pegelschwankungen aufu00adweisenden taktsignale (t1) or, for example, in a network access control of an annular internally generated approximately digital taktsignale (t2) in the head the level of the regenerated taktsignale (t1) to a taktu00adleitung controlled.the reform is based on early detection of pegelschwankungen in the way that the current to taktleitung durchgeschalteten (t1, t2) taktsignale are switched off and after a short delay, the other clock signal (t1, t2, each synchronized to taktleiu00adtung bu hold.
