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 appropriate 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’s output drives the output power stage which is capable of sinking the external coil currents of up to 0.5A.
