9.2Circuit Description
General Description
This LCD TV monitor using FL-1 platform. It can support PC analog signal ( via 15 pin D-Sub input ) and TV
signal. It support PIP function that is TV picture on PC graphic or TV picture on DVI /HDCP. It' s output resolution is
up to 1366X768 75Hz for WXGA panel.
It can support DVI HDCP digital signal input and also support TV (RF) , CVBS/ RG B signal ( from SCART1 I/O
for Europe model ) ,CVBS / YC ( from SCART2 I/O for Europe model ) , CVBS/YPbPr ( from Cinch I/O for Non-
Europe model ) , CVBS/YC ( from Cinch and S terminal I/O for Non-Europe model ) , and also have side I/O , support
CVBS/YC and Headphone for User easy used .
And It can also support Y Pb Pr signal input (from Cinch I/O) for 480I, 480P, 720P, 1080i 60Hz and 576I, 576P,
720P, 1080I 50Hz HDTV format input.
Note : For Chinch I/O model two components input is provided one for 480I,480P and 576I, 576P the other for
the 480I, 480P, 720P,1080i 60Hz and 576I, 576P, 720P, 1080I 50Hz HDTV format input.
It also have PVR output function , support and monitor all the CVBS signal output with L/R sound.
This LCD monitor TV use MST51512 as Scaler engine, which has embedded Analog D-sub, digital DVI decoder,
scaling input signal for panel, OSD and simple 3D de-interlace. The extra SDRAM is to accomplish video frame rate
conversion and PIP function.
The external CPU can be used for back light control, RC receiver, keypad input, I/O switch control , IIC
communication and TV tuning control, MSP34XX sound decoder control, SAA7119 video decoder control , Columbus
IC ( 3D- comb filter ) control , and Audio AMP TPA3004D sound control .
Video decoder SAA7119 is used for TV video processing and convert it with CCIR 601/16bits or 656/8bits digital
format and send to Columbus IC for 3D comb filter processing and noise reduction processing , after that then send
to Scaler for de-interlace process.
One audio decoder MSP34XXG is used for TV sound processing, and output to Class D audio amplifier
TPA3004D , then we can have 2 X10W audio output .
An option function in AP model Telttext display . Data decode is done by SAA5360, output RGB/FB is to video
decoder input for textoverlapping. In non-text model, this chip is N.C.
