vga to lvds panel converter
i know that this is no simple task!
But i want to convert the analog VGA signal to digital signals for a TFT panel.
i have my eyes on the AD9884 form analog devices.
this converts the analog video signals to digital. but the output is not
LVDS
outputs:
DRA7-0 Data Output, Red Channel, Port A 3.3 V CMOS 105–112
DRB7-0 Data Output, Red Channel, Port B 3.3 V CMOS 95–102
DGA7-0 Data Output, Green Channel, Port A 3.3 V CMOS 85–92
DGB7-0 Data Output, Green Channel, Port B 3.3 V CMOS 75–82
DBA7-0 Data Output, Blue Channel, Port A 3.3 V CMOS 65–72
DBB7-0 Data Output, Blue Channel, Port B 3.3 V CMOS 55–62
DATACK Data Output Clock 3.3 V CMOS 115
DATACK Data Output Clock Complement 3.3 V CMOS 116
HSOUT Horizontal Sync Output 3.3 V CMOS 117
SOGOUT Sync On Green Slicer Output 3.3 V CMOS 118
how can i convert the output to panel compatible LVDS?
the panel in mind is
LP141XA
inputs:
1VCC +3.3VDC Power Supply
2 VCC +3.3VDC Power Supply
3 GND Ground
4 GND Ground
5 RxIN0- LVDS Receiver Channel 0-
6 RxIN0+ LVDS Receiver Channel 0+
7 GND Ground
8 RxIN1- LVDS Receiver Channel 1-
9 RxIN1+ LVDS Receiver Channel 1+
10 GND Ground
11 RxIN2- LVDS Receiver Channel 2-
12 RxIN2+ LVDS Receiver Channel 2+
13 GND Ground
14 CKIN- LVDS Receiver Clock-
15 CKIN+ LVDS Receiver Clock+
16 GND Ground
17 NC No Connection
18 NC No Connection
19 GND Ground
20 GND
have anyone made simular conversion before? ?
any suggestions?
