ABSTRACT:
A delay line including analog delay elements each having a selectively adjusted coarse and fine delay portion is described. The coarse delay portion receives an input clock signal and generates a ramp signal having a slope based on a predetermined coarse delay setting. The fine delay portion generates a threshold voltage based on a predetermined fine delay setting. A comparator compares the coarse delay ramp signal voltage with the fine delay threshold voltage and generates an output clock signal when the ramp signal voltage surpasses the fine delay threshold voltage. The coarse delay is linearly adjustable based on a 32-bit binary input signal and the fine delay is binary-weight adjusted based on a 5-bit binary input signal. Both the coarse and fine delay portions are controlled by delay line control circuitry which compares a feedback version of the output clock signal with the input clock signal and provides control signals to increment or decrement coarse and fine delay in the delay line.
