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 output separately, making this  
IC suitable for S pins. There are also pins for analog RGB signal output, and each output pin has its own internal  
75driver.  
Applications  
TV peripherals  
Features  
1) Can be adapted for NTSC and PAL formats.  
2) Internal burst timing signal generator with half-H  
killer.  
5) Analog RGB signal output pins.  
6) Internal 75driver. (outputs color TV signals, lumi-  
nosity signals, chroma signals and analog RGB sig-  
nals)  
3) Internal flip-flop for PAL phase switching.  
4) Separate Y / C output pins.  
7) Adaptable for color subcarrier pulse input.
