The frequency range in which the AGC loop can
regulate the amplitude also depends on this ca-
pacitor.
The C- and S-corrections of shape serve to com-
pensate for the vertical deflection system non-line-
arity. They are controlled via
CCOR and SCOR
I2C bus controls.
Shape-corrected sawtooth with regulated ampli-
tude is lead to amplitude control stage. The dis-
charge exponential is replaced by VVOB level,
which, under control of the CONTROLLER, cre-
ates a rapid falling edge and a flat part before be-
ginning of new ramp. Mean value of the waveform
output on pin VOut is adjusted by means of
VPOS
I2C bus control, its amplitude through
VSIZE I2C
bus control. Vertical moiré is superimposed.
The biasing voltage for external DC-coupled verti-
cal power amplifier is to be derived from VRefO
voltage provided on pin RefOut, using a resistor di-
vider, this to ensure the same temperature drift of
mean (DC) levels on both differential inputs and to
compensate for spread of VRefO value (and so
mean output value) between particular devices.
10.4.2 - Vertical moiré
To blur the interaction of deflection lines with CRT
mask grid pitch that can generate moiré pattern,
the picture position is to be alternated at half-frame
frequency. For this purpose, a square waveform at
half-frame frequency is superimposed on the out-
put waveform’s DC value. Its amplitude is adjusta-
ble through
VMOIRE I2C bus control.
