The LM1886 is a TV video matrix D to A converter whirl encodes luminance and color difference signals from 3.bi red, green and blue inputs. The luminance °Abut Is encod ed from the NTSC equation Y — 0.3R * 0 59G — 0.111 and the R-Y and B-Y outputs are weighted to prevent over modulation. A built-in R-Y and burst gate polarity switch at low European PAL compatible signals to be encoded. A output levels including an RF 0 Carrier Ekes Voltage nevi been referenced to 5V for direct connection to the LM1881 N video modulator. When used In combinaban with thi LM1889 and a suitable sync generator, R, G and E information may be encoded to both composrle video arc RF channel camor .
