It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

Video A/D Converter
The MST6151 is a high
performance and fully integrated graphics processing IC solution for
multi-function LCD monitor/TV with resolutions up to SXGA/WXGA. It is
configured with an integrated triple-ADC/PLL, an integrated DVI/HDCP receiver,
a video de-interlacer, two high quality scaling engines, an on-screen display
controller, and a built-in output clock generator. By use of external frame
buffer, PIP is provided for multimedia applications. It
supports de-interlaced full-screen video, video-on-graphic overlay,
video-by-graphic split screen, frame rate conversion, and aspect ratio
conversion for various video sources. To further reduce system costs, the
MST6151 also integrates intelligent power management control capability for
green-mode requirements and spread-spectrum support for EMI management.
The VCT 49xxI is an IC
family of high-quality singlechip TV processors. Modular design and
deep-submicron technology allow the economic integration of features in all classes
of singlescan TV sets. The VCT 49xxI family is based on functional blocks
contained and approved in existing products like DRX 396xA, MSP 34x5G, VSP
94x7B, DDP 3315C and SDA 55xx.
Each member of the family contains the entire IF, audio, video, display, and
deflection processing for 4:3 and 16:9 50/60-Hz mono and stereo TV sets. The
integrated microcontroller is supported by a powerful OSD generator with
integrated Teletext & CC acquisition including on-chip page memory.
Video A/D Converter
Most flat-panel monitors
and projectors require a digital graphics input in order to accurately scale
and display graphics. The huge installed base of computers with analog video
graphics interfaces necessitates the use of a graphics digitizer to re-digitize
the analogue RGB signal before further processing.
■ The MST9883CR is a fully integrated analog interface for digitizing
high-resolution RGB graphics signals from PC’s and workstations. With a
sampling rate capability of up to 140 MHz, it can accurately support display
resolutions up to 1280x1024 (SXGA) at 75 Hz. The clamped input circuits provide
sufficient band width to accurately digitize each pixel.
■ The MST9883CR provides a high performance highly integrated solution to
support the digitization process, including the ADC’s, a voltage reference, a
PLL to generate the pixel sampling clock from HSYNC, clamping circuits, and
programmable offset and gain circuits to provide brightness and contrast
controls.
■ When the COAST signal is asserted, the PLL will maintain its output frequency
when HSYNC pulses are absent, such as during the VSYNC period in some systems.
■ A 32-step programmable phase adjustment control (0-360 deg) is provided for
the pixel sampling clock to adjust for the difference between the HSYNC edge
and RGB pixel edge timing.
■ The MST9883CR can send output data through one 24-bit port at the pixel clock
rate.
■ The MST9883CR can also support RGB to YCbCr conversion.
■ The MST9883CR has internal programmable pattern generator for testing.
■ The MST9883CR can accept either standard TTL, CMOS levels or saw tooth
vertical deflection signals for VSYNC input.
