LMC7532
Low EMI, Low Power XGA/SVGA TFT-LCD Column Driver
General description
The LMC7532 is a Column Driver suitable for Nation-
al’s Reduced Swing Differential Signalling (RSDS)
digital interface. It converts this 18-bit digital data into
analog voltage for 300 or 309 columns, charging each
sub-pixel to the correct gray level corresponding to the
digital value.
The RSDS path to the panel timing controller contrib-
utes toward lowering radiated EMI, reducing system
power consumption and eliminates one of the two pix-
el busses used in typical XGA TFT-LCD panels today.
This single 9-bit differential bus conveys the 18-bit
color data for XGA panels at 130Mb/s when using
VESA 60 Hz standard timing.
With the addition of a single National DS90CF364 or
‘564 FPD-Link™ chip, and the FPD63310 Universal
Interface XGA/SVGA Timing controller, the entire data
path is optimized for reduced EMI, power consump-
tion and width.
