Pixel-by-Pixel Adjustment of
Genlocking Phase
(ICS1522 Application)
To understand the operation of the pixel-by-pixel phase
adjust-ment feature, imagine that the modulus of the on-
chip divider is equivalent to the graphics system overall
divide.Also, imagine that the overflow of the internal
divider occurs at the same time as the overflow of the
graphics system line counter. Initial synchronization is
accomplished by switching from the external feedback
source (graphics system HSYNC) to the internal feedback.
Let us assume that we are now using the internal divider.
Now, imagine that the programmed value of the divider
(really a prescaler) is increased by one for a single pass-
through that prescaler (think of this as “swallowing” a
feedback pulse). We will lose exactly one CLK period of
phase in the feedback path. The VCO will speed up
momentarily to compensate for that, and re-lock the loop.
In doing so, the graphics system will receive exactly one
extra CLK cycle, advancing the phase of the graphics
system HSYNC by one CLK period relative to the reference
HSYNC. In a similar fashion, we can decrease the
programmed value of the prescaler (“adding” a pulse) to
retard the phase of the graphics system. Additionally, sub-
pixel phase adjustment is provided through varying the
voltage at the FINE input pin.
