Patent ID: 8390348

Claim:
A time base generator for providing a first clock signal and a second clock signal, the frequencies of said clock signals being different, said time base generator comprising: a clock signal generator providing the first clock signal at the first clock frequency; a first frequency divider configured to divide the first clock frequency by a first integer to produce a first auxiliary signal; a second frequency divider configured to divide the second clock signal by a second integer to produce a second auxiliary signal; a phase/period comparator comprising a first time to voltage converter receiving the first auxiliary signal, a second time-to-voltage converter receiving the second auxiliary signal and a voltage comparator connected to the first and a second time to voltage converter, the phase/period comparator being configured to generate an error signal by individually weighting and comparing the cycle durations or phasing of the first and second auxiliary signals; and a voltage-controlled oscillator controlled by the error signal to generate the second clock signal.
