UTC78045 pinout datasheet


The UTC78045 is a vertical deflection output for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component).

In a television (TV) or cathode ray tube (CRT) display, the vertical output integrated circuit (IC) is responsible for generating the vertical deflection signal that controls the movement of the electron beam across the screen in the vertical direction.

The vertical output IC is typically a specialized integrated circuit designed specifically for driving the deflection coils in a CRT display. These coils create a magnetic field that moves the electron beam vertically, allowing it to scan the entire screen from top to bottom.

The vertical output IC receives vertical synchronization signals from the TV’s circuitry, which are usually generated by the vertical sync separator circuit. Based on these signals, the vertical output IC generates the necessary waveform to drive the deflection coils and move the electron beam vertically.
