6 / 16 page Applications Information Figure 4 shows the block diagram of a typical analog RGB color monitor The RGB monitor is used with CADCAM work stations PC’s arcade games and in a wide range of other applications that benefit from the use of color display terminals The RGB color monitor characteristics may differ in such ways as sweep rates screen size CRT color trio spacing (dot pitch) or in video amplifier bandwidths but will still be generally configured as shown in Figure 4 Separate horizontal and vertical sync signals may be required or they may be contained in the green video input signal The video input signals are usually supplied by coax cable which is terminated in 75X at the monitor input and internally ac cou- pled to the video amplifiers These input signals are approxi- mately 1 volt peak to peak in amplitude and at the input of the high voltage video section approximately 6V peak to peak At the cathode of the CRT the video signals can be as high as 60V peak to peak One important requirement of the three video amplifiers is that they match and track each other over the contrast and brightness control range The Figure 4 block labeled ‘‘VIDEO AMPLIFICATION WITH GAIN AND DC CONTROL’’ describes the function of the LM1203 which contains the three matched video amplifiers contrast control and brightness control TLH9178 – 4 FIGURE 4 Typical RGB Color Monitor Block Diagram http www nationalcom 6 |
