Product specification
Horizontal and vertical deflection controller
for VGA/XGA and multi-frequency monitors
TDA4850
Notes to the Characteristics
1.
∆Io/∆t relative to value of mode 3.
2. Parabola amplitude tracks with mode-dependent vertical amplitude but not with vertical amplitude adjustment.
Tracking can be achieved by a resistor from vertical amplitude potentiometer to pin 14.
