Multimedia ICs Color TV Signal Encoder BH7236AF The BH7236AF converts analog RGB signals into color TV signals in the NTSC and PAL formats. From inputs of analog RGB signals, a composite synch signal, burst pulses and a color carrier, this IC generates a color TV signal, and can be adapted for either NTSC or PAL standards, which are selected externally. When set to PAL, chroma phase is switched for each line. The chroma signals and luminosity signals can be combined into a color TV signal or ou.
