The TDA9108 is a horizontal deflection processor specially designed for monitor applications. The H-drive output duty cycle, the horizontal frequency and the horizontal position are DC adjustable ; it accepts both POS/NEGpolarity on sync input and delivers polarity information on a dedicated pin. All these features make the device a good choice for multifrequency application.In addition tothis,X-ray protection, 2 complementary H-drive output , and a back porch clamping pulse generator are also included. TDA9108 is a monolithic integrated circuit encapsulated in a 14 lead dual line plastic package.
