DESCRIPTION

The TDA9109/N is a monolithic integrated circuit assembledin32-pinshrinkdual in lineplasticpackage.ThisIC controlsall thefunctionsrelatedtothe horizontal and vertical deflection in multimode or multi-frequencycomputerdisplaymonitors.

The internal sync processor, combined with the very powerful geometrycorrection block makethe TDA9109/N suitable for very high performance monitors,using very few externalcomponents.

Thehorizontaljitter levelisverylow.Itisparticularly well suited forhigh-end 15” and 17” monitors.

Combined with the ST7275Microcontroller family, TDA9206 (Video preamplifier) and STV942x (OnScreen Display controller) the TDA9109/N allows fullyI

Cbus controlled computer display monitors to be built with a reduced number of external components.

6. This PLL capturerange may be obtained only if f0is adjusted (for instanceby adjusting R0) . If not, more marginmust be provided between f

(Min.) and f0, to cope withthe components spread.
