Delay LinesDelay lines are a type of clock and timing IC that are used to introduce a precise delay to a digital signal. They can be used to synchronize signals between different parts of a circuit, or to adjust the timing of a signal to match the requirements of a particular system. Delay lines can be implemented using a variety of technologies, such as digital logic, analog delay elements, or optical fibers. The specific implementation will determine the accuracy and range of the delay that can be introduced.
