  • Delay locked loops with calibration for external delay
    Patent number: 11936389
    Abstract: Provided herein are delay locked loops (DLLs) with calibration for external delay. In certain embodiments, a timing alignment system includes a DLL including a detector that generates a delay control signal based on comparing a reference clock signal to a feedback clock signal, and a controllable delay line configured to generate the feedback clock signal by delaying the reference clock signal based on the delay control signal. The timing alignment system further includes a delay compensation circuit that provides an adjustment to the controllable delay line to compensate for a delay of the feedback clock signal in reaching the detector.

  • Timing alignment systems with gap detection and compensation
    Patent number: 11177815
    Abstract: Provided herein are gap detection and compensation schemes for timing alignment systems. In certain embodiments, a timing alignment system includes a detector that generates one or more loop control signals based on comparing a reference clock signal to a feedback clock signal, a loop filter having a loop voltage that is adjusted based on the one or more loop control signals, and a gap detection and compensation circuit that processes the one or more loop control signals to detect a gap in at least one of the reference clock signal or the feedback clock signal. In response to detecting the gap, the gap detection and compensation circuit modifies the one or more loop control signals to provide an adjustment to the loop voltage.
