GENERAL DESCRIPTION
The MST706 is a high quality ASIC for NTSC/PAL/SECAM car TV application. It receives analog
NTSC/PAL/SECAM CVBS and S-Video inputs from TV tuners, DVD or VCR sources, including weak and distorted signals, as well as analog YCbCr input from HDTV/SDTV systems. Automatic gain control (AGC) and 10-bit A/D converters provide high resolution video quantization. With automatic video source and mode detection, users can easily switch and adjust variety of signal sources. Multiple internal adaptive PLLs precisely extract pixel clock from video source and perform sharp color demodulation. Built-in line-buffer supports adaptive 2-D comb-filter, 2-D sharpening, and synchronization stabler in a condense manner. The output format of MST706 supports 6-bit TTL/TCON digital TFT-LCD modules.

REVISION HISTORY
Document Description Date MST706_pb_v01
? Initial release
03/20/2014
Electrostatic charges accumulate on both test equipment and human body and can discharge without detection. MST706 comes with ESD protection circuitry; however, the device may be permanently damaged when subjected to high energy discharges. The device should be handled with proper ESD precautions to prevent malfunction and performance degradation.
