Abstract
A delay locked loop device is provided, which includes a receiver, a delay line, a frequency detection and control circuit, a phase detector, and a delay control circuit. The receiver compares an input clock signal and a reference voltage to generate a first signal, and generate a reference clock signal based on the input clock signal. The delay line delays the first signal to generate a second signal based on a delay control signal. The frequency detection and control circuit detects an operating frequency of the reference clock signal to generate an enable signal. The phase detector detects, in response to the enable signal, a phase difference between the reference clock signal and a feedback clock signal to generate a phase detection result. The delay control circuit is configured to generate the delay control signal for the delay line based on the phase detection result.
