1 FEATURES 2 GENERAL DESCRIPTION
TDA4882
• 85 MHz video controller • Fully DC controllable • 3 separate video channels • Input black-level clamping • White level adjustment for 2 channels only • Brightness control with correct grey scale tracking • Contrast control for all 3 channels simultaneously • Cathode feedback to internal reference for cut-off control, which allows unstabilized video supply voltage • Current outputs for RGB signal currents • RGB voltage outputs to external peaking circuits • Blanking and switch-off input for screen protection • Sync on green operation possible • On Screen Display (OSD) facility.
