Clock Deskew
The DCM contains a delay-locked loop (DLL) to completely eliminate clock
distribution delays, by deskewing the DCM's output clocks with respect to the input
clock. The DLL contains delay elements (individual small buffers) and control logic.
The incoming clock drives a chain of delay elements, thus the output of every delay
element represents a version of the incoming clock delayed at a different point.
The control logic contains a phase detector and a delay-line selector. The phase
detector compares the incoming clock signal (CLKIN) against a feedback input
(CLKFB) and steers the delay line selector, essentially adding delay to the output of
DCM until the CLKIN and CLKFB coincide.
