A delay loop (e.g., a voltage-controlled delay loop) has (at least) two devices (e.g., interpolators) for generating clock signals for injection into the delay elements of the delay loop in a leap-frog manner, in which, while one interpolator is generating the clock signal currently selected for injection, the other interpolator can be controlled to generate the next clock signal to be selected for injection. This leap-frog technique can provide more settling time for generating injected clock signals than implementations that rely on a single interpolator.
