The variable delay is split into two delay elements:
1. Fine delay
2. Coarse delay
The Variable Delay is the sum of Fine Delay and Coarse Delay. If a de-skew between
channel 1 and channel 2 is needed, adjust in the first step the coarse delay to the
optimum position. In the second step, use the fine delay to perfectly align both
channels.
