ROHM Semiconductor BA7232FS
The BA7232FS converts analog RGB signals into color TV signals in the NTSC and PAL formats. 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.| Part No. | BA7232FS |
