Abstract
A data signal delay system may include a delay unit and a phase interpolation unit. The delay unit may include multiple delay elements that each have an element delay. The delay unit may be configured to generate multiple delay signals by delaying a data signal using the delay elements such that each of the delay signals has a different delay. The phase interpolation unit may be coupled to the delay unit and may include a mixer. The mixer may be configured to mix two of the delay signals based on mixing weights selected for the two delay signals to generate a final delayed data signal that is the data signal delayed by a final delay. The mixing weights may be selected based on the final delay.
