c-1. ADC Converter
:AD9888
The AD9888 is a complete 8 bit , 205 MSPS monolithic analog interface
optimized for capturing RGB graphics signals. Its 205 MSPS encode rate
capability and full-power analog bandwidth of 500 MHz supports resolutions up
to UXGA(1600 x1200 @ 75 Hz).
c-2 TMDS Receiver:
SIL153BCT100
The Sil153BCT100 receiver uses Panel Link Digital technology to support high
resolution displays up to SXGA (25MHz~112MHz). The Sil153B receiver
supports up to true color panels (24 bit/pixel, 16.7M colors) in 1 or 2 pixels/clock
mode. In addition, the receiver data output is time staggered to reduce ground
bounce that affects EMI.
c-3 VIDEO Decoder:
SAA7118E
The SAA7118E decoder is a ADC too, but it can deal with the ordinary TV
signals. The SAA7118E can input Composite (fig.A)
、
S-video (fig.B)
、
Component
(fig.C) and its outputs are digital Y(Luminance) , C (Chromacity) signals. And
also can adjust brightness, contrast, saturation, hue.
c-4 De-interlace:
SIL504CM208
The Sil504 transfer interlacing signals to progressive signals. The advantage of
progressive signals is that the scanning rate doubling to let the screen more
stable and non-flickering. Besides, the sources of input may have 24 0r 30 or 25
frames per sec, so the de-interlaced chip shall tell from the differences and
processing the signals. The basic principle of de-interlaced IC is combined the
odd and even fields to a frame, and the processing needs a memory IC(SDRAM)
to stock these signals for processing . For the improving the quality of image
sake, more and more TVs or DVD players all have the functions of progressive
scanning.
