Starting from the vertical ramp, a parabola shaped current is generated for E/W correction, dynamic horizontal
phase control correction, and vertical dynamic focus correction.
The base of the parabola generator is an analog multiplier, the output current of which is equal to:
I = k
×
(V
OUT
- V
DCMID
)
2
Where Vout is the vertical output ramp (typically between 2 and 5V) and V
DCMID
is 3.5V (for V
REF-V
= 8V). One
more multiplier provides a current proportional to (Vout - V
DCMID
)

for corner correction The VOUT sawtooth is
typically centered on 3.5V. By changing the vertical position, the sawtooth shifts by
±
0.3V.
In order to keep a good screen geometry for any end user preference adjustment we implemented the geometry
tracking.
Due to large output stages voltage range (E/W, keystone, corner), the combination of tracking function with
maximum vertical amplitude, max or min vertical position and maximum gain on the DAC control may lead to the
output stages saturation. This must be avoided by limiting the output voltage by appropriate I
2
C registers values.
For E/W part and dynamic horizontal phase control part, a sawtooth shaped differential current in the following
form is generated:
I
’
= k

(V

Then
I and
I
’
are added together and converted into voltage for the E/W part.
Each of the three E/W components, and the two dynamic horizontal phase control ones may be inhibited by their
own I

C select bit.
The E/W parabola is available on pin 24 via an emitter follower which has to be biased by an external resistor
(10K
). Since stable in temperature, the device can be DC coupled with an external circuitry.
The vertical dynamic focus is available on output pin 10. Dynamic horizontal phase control current drives internally
the H-position, moving the Hfly position on the horizontal sawtooth in the

Function
When the Synchronization pulse is not present, an internal current source sets the free running frequency. For an
external capacitor, C

= 150nF, the typical free running frequency is 100Hz.
