GENERAL  DESCRIPTION
The MST705 is a highquality ASIC for NTSC/PAL/SECAM car TV application. It receives analog NTSC/PAL/SECAM CVBS and S-Video inputs fromTVtuners, DVDor VCR sources, including weak anddistorted signals, as well as analog YCbCr input from HDTV/SDTV systems. Automaticgain control(AGC) and 10-bit 3-channel A/D convertersprovide high resolution video quantization. With automatic video source and mode detection, users can easily switch and adjust varietyof signal sources.
