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
75Ω driver.
Applications
TV peripherals
Featuresadapted for NTSC and PAL formats.
1) Can be
2) Internal burst timing signal generator with half-H
killer.
3) Internal flip-flop for PAL phase switching.
4) Separate Y / C output pins.
5) Analog RGB signal output pins.
6) Internal 75Ω driver. (outputs color TV signals, lumi-
nosity signals, chroma signals and analog RGB sig-
nals)
7) Adaptable for color subcarrier pulse input.
