Design Insights (Important)

Crystal accuracy (8MHz) is critical for timing stability
Interrupt handling must be carefully configured in firmware
Proper grounding and separation of analog/digital sections required
Sync signal integrity directly affects picture stability
ROM is fixed → firmware customization is limited to specific variants

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.
