... LOW DISSIPATION ■ FEW EXTERNAL COMPONENTS ■ DESCRIPTION The TEA2031A is intended to ensure frame rate modulated parabolic and keystone corrections to the horizontal deflection circuitry of 110° color TV sets. The linear frame saw-tooth is applied to appropri- ate circuitry from which a corresponding parabolic waveforms is obtained. This waveform is then fed to a comparator together with the linear line saw- tooth for comparison. Comparator’ ...

... Line SAW-TOOTH 100Ω 50µA Frame SAW-TOOTH GENERAL DESCRIPTION The TEA2031A is intended to provide to 110° color TV sets a parabolic and keystone frame rate mod- ulated correction in addition to the main horizontal scanning. A stable 6.3V internal reference provides current and voltage references to the whole IC. ...
