Color TV Signal Encoder

BA7232FS

The BA7232FS 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, the

BA7232FS changes chroma phase according to the burst flag pulses.

The chroma signals and luminosity signals can be combined into a color TV signal or output separately, making this

IC suitable for S pins. Also, this IC comes with an output pin for the analog RGB signal. Each output has a built-in

75Ω driver.

Applications

•

TV peripherals

Features

•

1) Can be adapted for NTSC and PAL formats.

2) Internal flip-flop for PAL phase switching.

3) Separate Y / C output pins.

5) Internal 75Ω driver. (outputs color TV signals, lumi-

nosity signals, chroma signals and analog RGB sig-

nals)

4) Analog RGB signal output pins.

6) Adaptable for color subcarrier pulse input.
