    Abstract: Digital controlled delay lines are provided. A digital controlled delay line includes a plurality of delay cells coupled in a chain forming a propagation path to propagate an input signal and to delay the input signal by a delay time. The propagation path is formed when a single delay cell is operated in a feedback mode, the delay cells previous to the single delay cell in the chain are operated in a propagation mode, a subsequent delay cell following the single delay cell in the chain is operated in a standby mode, and the delay cells following the first subsequent delay cell in the chain are operated in an idle mode.

    Abstract: An electronic system includes transmitting circuitry of a first clock domain and receiving circuitry of a second domain. The transmitting circuitry re-times a digital input signal with rising edges of a clocking signal of the first clock domain when a phase of the clocking signal of the first clock domain leads a phase of a clocking signal associated with the digital input signal. Otherwise, the transmitting circuitry re-times the digital input signal with falling edges of the clocking signal of the first clock domain when the phase of the clocking signal of the first clock domain does not lead the phase of the clocking signal associated with a digital input signal. The receiving circuitry receives the re-timed digital input signal from the transmitting circuitry. Thereafter, the receiving circuitry re-times the re-timed digital input signal with rising edges of a phase of a clocking signal associated with the re-timed digital input signal when the phase of the clocking signal associated with the re-timed digital input signal leads a phase of a clocking signal of the second clock domain. Otherwise, the receiving circuitry re-times the re-timed digital input signal with falling edges of the phase of a clocking signal associated with the re-timed digital input signal when the phase of the clocking signal associated with the re-timed digital input signal does not lead the phase of a clocking signal of the second clock domain.
