... Advanced PAL/NTSC Encoder The MC13077 is a high quality RGB/YUV to NTSC/PAL encoder with Composite Video and S–Video outputs. The IC integrates the color difference and luma matrix circuitry, chroma modulators, subcarrier oscillator, and logic circuitry to encode component video into a composite video signal compatible with the NTSC/PAL standards. The IC operates off a standard + 5 ...

... RGB inputs should be cap–coupled to ground. In either case, composite sync still needs to be input to the MC13077 at Pin 7 (see Figures 11, 12 and 13). If the R–Y and B–Y inputs also have burst flag, it can also be input along with the color difference signals at these pins. ...

... If the MC13077 is encoding 525/60 component video to NTSC and the MC13077 is generating the burst flag, the start of burst will occur 18 counts after the leading edge of sync has been sampled, and will continue until nine cycles of burst have occurred. Since the reset pulse of the 9– ...

There is also an internal delay on the order of 100 ns due to internal filtering that must be considered. Thus a 400 ns luma delay line is used to equalize the timing of the luma and the chroma ...

... Pin 19 low when the squarewave is high. The component envelopes with the proper PAL burst phase are then modulated to produce the composite chroma. If the MC13077 is encoding to NTSC, only the B–Y color difference component is provided a negative burst flag. This envelope when modulated results in the characteristic –180 phase difference between the color burst and the subcarrier for the B– ...
