Multimedia ICs 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 combine.

Color TV Signal Encoder

Multimedia ICs 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. 4) Analog RGB signal output pins. 5) Internal 75Ω driver. (outputs color TV signals, luminosity signals, chroma signals and analog RGB signals) 6) Adaptable for color subcarrier pulse input. •Block diagram BIN 1 CLAMP BFP GIN 2 CLAMP BFP RIN 3 CLAMP BFP VCC MATRIX BURST GEN.
