Fixed-Phase Shifting
In
in phase with the desired clock phase. The clock outputs are phase-shifted to appear
sometime later than the input clock, and the LOCKED signal is asserted.

Clock Event 1
Clock event 1 appears after the desired phase shifts are applied to the DCM. In this
example, the shifts are positive shifts. CLK0 and CLK2X are no longer aligned to
CLKIN. However, CLK0, and CLK2X are aligned to each other, while CLK90 and
CLK180 remain as 90° and 180° versions of CLK0. The LOCK signal is also asserted
once the clock outputs are ready.
2-18, the DCM outputs the correct frequency. However, the clock outputs are not
