Abstract
The present disclosure provides for calibrating clock signals in an unmatched data input system. In various embodiments, an unmatched data input system uses multi-delay circuits to calibrate a clock signal distributed to various input/outputs in the unmatched data input system. These multi-delay circuits can include coarse delay circuits and fine delay circuits that provide a broad range as well as accurate delay capabilities. Through the use of these multi-delay circuits, the unmatched data input system can optimally align a clock signal with its associated data signal across multiple input/outputs.
