MEHRKANALIGER FEHLERTOLERANTER TAKTGEBER

摘要

A fault-tolerant clock having at least four channels, each providing its own clock output, and yet all clock output signals of all functioning channels being coherent with one another. One clock functions as a master with the other clocks of the remaining channels slaving themselves to that one clock. In view of a failure of the master, another clock reigns as the master clock to slave the remaining clocks. If the next master clock fails, then still another clock becomes a master to slave the remaining clock or clocks. The clocks are independently powered such that complete failure of one clock, including its power, does not necessarily prevent the other clocks from providing coherent outputs.
