TDA9109A
For the E/W part and the dynamic horizontal
phase control part, a sawtooth-shaped differential
current in the following form is generated:
Then I and I’ are added and converted into volt-
age for the E/W part.
Each of the two E/W components or the two dy-
namic horizontal phase control components may
be inhibited by their own I

The E/W parabola is available on Pin 24 via an
emitter follower output stage which has to be bi-
ased by an external resistor (10
Since stable in temperature, the device can be DC
coupled with external circuitry.
The vertical dynamic focus is combined with the
horizontal focus on Pin 10.
The dynamic horizontal phase control drives inter-
nally the H-position, moving the HFLY position on
the horizontal sawtooth in the range of
both for side pin balance and parallelogram.
