... Nov 26 2 GENERAL DESCRIPTION The TDA4884 is an RGB pre-amplifier for colour monitor systems with SVGA performance, intended for coupling of the colour signals to the cathodes of the CRT. With special advantages the circuit can be used in conjunction with the TDA485x monitor deflection IC family ...

... FUNCTIONAL DESCRIPTION The RGB input signals 0.7 V (p-p) are capacitively coupled into the TDA4884 (pins 2, 5 and 8) from a low ohmic source and are clamped to an internal DC voltage (artificial black level). Composite signals will not disturb normal operations because an internal clipping circuit cuts all signal parts below black level ...

... Cut-off level: corresponding DC voltage at CRT cathode in closed feedback loop. d) Black level: actual signal black level at either voltage outputs or cathode. At voltage outputs the black level is equal to reference black level because there is no brightness control via TDA4884. At cathode the black level is equal to cut-off level. Brightness can be adjusted via grid 1. ...
