... Sep 04 2 GENERAL DESCRIPTION The TDA4882 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 ...

... General Figure 4 illustrates the signal processing. The RGB input signals 0.7 V (p-p) are capacitively coupled into the TDA4882 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 ...
