Figure 17. Phase Adjustment Delay Curve
It is common for LCD monitor applications for the end user to change the sampling phase in
equally stepped intervals. Equally spaced time delays can be implemented using several
programming techniques:
1) LUT approach. A look-up-table is developed with entries representing equally spaced time
delays. Multiple LUTs or changing the step size within a LUT can be used to increase the
quantization of the time delay. The Genesis firmware utilizes a LUT with 150ps entries and
changes the step size depending on the mode detected. This is the recommended method.
2) Piece-wise linear connected lines. In this case, the resultant curve can be approximated with
a number of line segments connected vertix-to-vertix. The firmware would be responsible to
select the appropriate line (and therefore the appropriate equation) based on total delay
required. Please contact Genesis for line equations if required.
