Patent ID: 8462840

Claim:
A digital to time converter for generating a first output signal and a second output signal separated by a predetermined delay, comprising: a first periodic signal generator generating a first periodic signal with a first period; a second periodic signal generator generating a second periodic signal with a second period; a periodic signal synchronizer coupled to the first periodic signal generator and the second periodic signal generator and comprising: a phase detector detecting a phase difference between the first periodic signal and the second periodic signal, and outputting a phase indication signal; a first output pulse generator, comprising: a first counter starting a count according to the first periodic signal when the phase indication signal is asserted to indicate that a phase of the first periodic signal coincides with a phase of the second periodic signal, wherein when a first value is counted, the first output pulse generator outputs a pulse as the first output signal; and a second output pulse generator, comprising: a second counter starting a count according to the second periodic signal when the phase indication signal is asserted to indicate that a phase of the first periodic signal coincides with a phase of the second periodic signal, wherein when a second value is counted, the second output pulse generator outputs a pulse as the second output signal, wherein the predetermined delay relates to the first value, the second value and a difference between the first period and the second period.
