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 .

In Nafta model CC,V-chip data is decoded in SAA7119 and the scaler OSD display the CC information. The V-Chip is decode by SAA7119

and control via the MCU. In Europe model "Teletext display". Data decode is done by SAA5360, output RGB/FB is to video decoder input for

text overlapping. In non-text model( Nafta. Etc.), this chip is Not used .
