ogy. The multiplexer function includes the selection and mixing of analog and digital signals. The chip consists of 4 
channels (x 2). A digital signal through the control terminal turns on the switch of a corresponding channel.
· IC3002 :  VIDEO PROCESSOR 
   Part number:  
VCTP
   Sharp code:  
RH-IXB698WJZZQ
The VCT 6wxyP family is dedicated to high-quality FPD and double-scan TV sets. The memory and program ROM 
are integrated in the IC. Modular design and deep submicron technology allow the integration of audio, video, tele-
text, OSD, and controller-related functionalities. They cover the whole range of flat-panel display TVs. The IC is 
based on proven functional blocks of existing products like VCT 49xxI, VSP 94x5B, and DPS 94xxB.
Each member of the IC family contains the entire audio, video, upconversion processing for 4:3 and 16:9 50/60 Hz 
progressive or 100/120 Hz interlaced stereo TV sets plus the control/data interface for flat-panel displays. The inte-
grated microcontroller is supported by a powerful OSD and graphics generator with integrated teletext acquisition.
The VCT 6wxyP family provides a front-end video processing unit with 4 CVBS-Y/C or component inputs for HDTV, 
EDTV, and SDTV. A VBI slicer, support of 1000 pages of teletext, and a 3-D comb filter for PAL and NTSC (in certain 
versions) are also available. The front-end unit further allows to process an SD and an HD source in parallel, thus 
enabling PiP and PaP functionality. Motion-adaptive de-interlacing, temporal noise reduction, and film mode detec-
tion are based on a unified memory technology. 
Post-scaling in the display processing block ensures the desired output format. Display processing is supported by 
an 8-bit 8051-compatible controller. By means of powerful alpha-blending, the graphics mixer composes the output 
image from following image layers: the video layer, the OSD layer and the pixel graphics layer.
The audio part consists of a multistandard sound IF demodulator and a baseband processor supporting all desired 
sound features in this range.
A connection for additional features, such as advanced motion compensation via -Micronas’ FRC 94xyA, is also 
provided.
