CH7002D Scalable VGA to NTSC/PAL Encoder

Chrontel’s CH7002 VGA to NTSC/PAL encoder is a standalone integrated circuit which provides a PC 99 compliant solution for TV output. It accepts RGB analog inputs directly from VGA controllers and converts them directly into NTSC or PAL TV format, with simultaneous composite and S-Video outputs. This circuit integrates a digital NTSC/PAL encoder with 8bit AD.
