n DVI-I connector
n Long Distance DVI
- option (up to 50m, with high quality cable)
Video(SDTV):
n 10-Bit 4x oversampling
n 3 rd gen. Motion Adaptive De-Interlace
n CTI color transient improvement
n DNR digital noise reduction
n 5-line super adaptive 2D comb filters
n Video Inputs: 2xFBAS (CVBS / Cinch), 1xY/C (SVideo / miniDIN)
and at pin header another 7 inputs (3xY/C or 11xFBAS)
n Video-Norm: PAL, SECAM, NTSC auto detect
n Frequency-Locking for true 50Hz video
n Additional input modules for (HDSDI / SDSDI)
n Picture-in-Picture (PiP) and Picture by Picture (PbP)
ADI99DVI
The ADI99DVI is backwards compatible with the ADI99, with
respect to outlines, connectors and function. The additional DVI
input is new. TFT panels (TTL / LVDS) with resolutions up to
1280x1024 are supported. RGB, DVI, 2xFBAS and Y/C may be connected
at the same time. Both manual and automatic inputs can
be selected.
Features
Display:
n Resolution QVGA(320x200) to SXGA(1280x1024).
n Panel detection, automatic selection of panel power and timing.
n No programming of panel files necessary. Firmware
includes the timings of any adapted panel.
n Easy warehousing, one board fits to all panels
n Frame Rate Converter. The panel is always driven with the
specified timing, regardless of the input source.
n High quality arbitrary scaling engine using (SmartScaling-2TM)
technology to fit the input image to panel resolution.
n Dynamic Dithering makes a 18-Bit panel look like a true colour
device.
n LVDS interface for single and dual pixel panels
n TTL interface for single and dual pixel panels
Inputs with selectable scan sequence
RGB:
n 15-pin VGA connector and pin header 2,54mm 2
n Synchronization: H/V, C-Sync, SyncOnGreen
n Viewable Timing:
n Max. 1280x1024 (SXGA)
n Max. 200Hz vertical refreshrate
n Min. 15 MSPS
n Interlaced signals are supported
DVI:
n Using DVI-I connector on additional adaptor board
Video:
n Video-Inputs: 4xFBAS (CVBS / Cinch) and 2xY/C
(SVideo / miniDIN)
n Video-Norm: PAL, PAL60, SECAM, NTSC autodetect
n Motion Adaptive De-Interlace important for proper
de-interlacing.
n Frequency-Locking to avoid image judder provoked
by 50Hz -> 60Hz conversion
