CH7024 chip provides an interface between the SAM9M10 LCD Controller and a TV set
by converting LCD signals to TV signals.
The CH7024 is a TV encoder device which encodes the video signals and generates synchronization
signals for NTSC and PAL standards. Supported TV output formats are NTSC-M, NTSC-J, NTSC-433,
PAL-B/D/G/A/I, PAL-M, PAL-N and PAL-60. The CH7024 provides video output support for CVBS or S-
video.
