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 that the phase relationship has changed such that it no longer meets the slave specification.
