Abstract

Clock-controlled circuitry organised into at least first and second clock domains, the first clock domain configured to operate based on a first clock signal and the second clock domain configured to operate based on a second clock signal, wherein: the first clock domain comprises a first signal generator operable to generate a first repetitive signal synchronised to the first clock signal; the second clock domain comprises a second signal generator operable to generate a second repetitive signal synchronised to the second clock signal; the first signal generator is operable, when operating in master mode, to output to the second signal generator a first synchronisation signal indicative of a phase of the first repetitive signal; and the second signal generator is operable, when operating in slave mode, to: set a timing of the second repetitive signal relative to the second clock signal based on the first synchronisation signal so that the second repetitive signal is set to have a phase relationship with the first repetitive signal which then meets a slave specification; and re-set the timing of the second repetitive signal relative to the second clock signal if it is determined th…
