MST719DE lcd tv processor

 

Description

The MST719DE is a high quality ASIC for NTSC/PAL/SECAM, and HDMI LCD-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 RGB and YCbCr. Automatic gain control (AGC) and 10-bit 3-channel 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 MST719DE supports programmable 8-bit TTL or LVDS digital or mini-LVDS digital TFT-LCD modules.

FNR-10K471 varistor

Description

In general, withstanding surge current is max. Pulse current value which determined by test conditions such as wave-shape, shock times and interval time etc, the change ratio of Varistor Voltage should be less than ±10% of the initial Value. The shock time is the function of wave – shape, amplitude and interval time ,when the amplitude decrease to 50% of the initial, it should be increased to 2 times of the initial in order to keep the life longer, the surge current which is absorbed by the varistor should be less than max. Withstanding surge current.
