... STV9211 2 FUNCTIONAL DESCRIPTION 2.1 RGB input, clamping function The three RGB inputs have to be supplied with a video signal (maximum peak-to-peak value = 1V) through coupling capacitors (100 nF typ.). The RGB inputs include a clamping function using the input serial capacitor as “memory capacitor”. To avoid the discharge of this capacitor during the line (due to leakage current), the input voltage is referenced to the ground ...

... InfraBlack adjustment procedure (Cut-off) The STV9211 allows to adjust independantly the InfraBlack levels of the 3 video outputs with a high resolution. This ajustment is done via the 3 infra-black level registers (IBL1, IBL2 and IBL3). In order to have the optimum resolution necessary, first, to set the video signal inside the linear area of the amplifier, by programing the infra-black range register IBR (26 or 36V) and the infra- black offset register IBO ...
