TEA2031A屬于集成電路（IC）的視頻處理。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的TEA2031A視頻處理一種集成電路 (IC) 半導(dǎo)體器件，設(shè)計用于在放大、增強、編碼器和解碼器（編解碼器）、緩沖、校準(zhǔn)、處理、信號調(diào)節(jié)、調(diào)制與解調(diào)、轉(zhuǎn)換、傳輸、伽瑪校正、切換、OSD、數(shù)字化和多路復(fù)用等應(yīng)用中處理音頻和/或視頻信號。

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.
