MAJOR ICs INFORMATION
1. General ICs Information
XD603WJ (MAIN UNIT):
· IC1905 : HDMI RECEIVER
The Sii9021 is a second generation panel link cinema receiver that is compatible with the HDMI 1.1 (High Deﬁnition
Multimedia Interface) speciﬁcation. The Sii9021 is capable of receiving and outputting two channel digital audio sig-
nals at up to 192 kHz— an excellent solution for digital TVs.
This IC features the following.
1) Digital video interface supports video processors.
2) Analog RGB and YPbPr output: 10-bit DAC.
3) Digital audio interface supports high-end audio systems.
· IC1901 : NVM OF HDMI (E-EDID)
This IC is a 2-wire (I2C bus type) serial EEPROM this is electrically programmable. This EEPROM chip stores the
data structure used to carry conﬁguration information for optimal use of a display (EDID data).
· IC2701 : SYNC SELECT
This VHC153 is a high-speed Dual 4-input multiplexer with common select inputs and individual enable inputs for
IC2704 : HDMI & RGB SOUND MULTIPLEXER
The TC74HC4052A is a high-speed CMOS analog multiplexer/demultiplexer backed by silicon gate CMOS technol-
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
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
