... Invert operation is carried out with SIGCEN (Pin 35) potential as center voltage of signal inversion. OFFSET (Pin 48) input voltage corresponds to 100% white level of the signal input to VIDEO_IN. When used in combination with the CXA2111R, connect the CXA2111R V33 (Pin 8) output to the CXA2112R OFFSET. When use DA converter output as the VIDEO signal, connect DA converter maximum output voltage (normally, DA converter's supply voltage) ...

... Operation Mode Setting 1) For each RGB channel, LCX016 requires demultiplexed 6 analog outputs (one CXA2112R), and LCX017 needs 12 (two CXA2112R). In either case, scan direction switching, sample-and-hold position and phase can be controlled. The mode input pin settings for each case are shown below. ...

... H Table A-2 R1 sets the level for setting values 1 and 2. The appropriate resistance value changes depending on numbers of CXA2112R are driven by one CMOS logic (1-channel or RGB 3-channel drive, or one CXA2112R (6- outputs/ch) or two CXA2112R (12-outputs/ch)). Recommended resistance values are given in Table A-3. CMOS Logic Connection ...
