The TDA9110 is a monolithicintegrated circuit assembledin 32-pin shrunkdual in line plasticpackage.This IC controlsall thefunctionsrelatedto the
horizontal and vertical deflection in multimode or
multi-frequencycomputerdisplaymonitors.
Theinternalsynchroprocessor, combinedwith the
very powerful geometrycorrectionblock make the
TDA9110suitablefor very high performancemonitorswith very few externalcomponents.
Thehorizontal jitter level is extremelylow.(Typical
standarddeviation : 300ps @ 31kHz).
Itisparticularlywellsuitedforhigh-end15” and 17”
monitors.
Combined with ST7275 Microcontroller family,
TDA9206 (Video preamplifier) and STV942x
(On-Screen Display controller)the TDA9110
allows to built fully I
display monitors, with a reduce number of external components.

Notes : 4. With Register07 at Byte x0xxxxxx (VerticalS-Correction Control) then the S correction is inhibited, consequentlythe sawtooth has
a linear shape.
5. WithRegister 08 at Byte x0xxxxxx (VerticalC - Correction Control) then the C correction is inhibited, consequently the sawtooth
has a linear shape.
6. It is the frequency range for which the VERTICAL OSCILLATOR will automaticallysynchronize, using a single capacitor value on
Pin 22 and with a constant ramp amplitude.
