FPD63310
Universal Interface XGA Panel Timing Controller (UI-XPAT)
Reduced Swing Differential Signaling (
RSDS )
General Description
The FPD63310 is the first TFT-LCD timing controller that
combines at TTL single pixel system interface with Nation-
al's Reduced Swing Differential Signaling (RSDS) source
driver interface. It resides on the TFT-LCD panel and pro-
vides the data buffering and control signal generation for
XGA and SVGA TFT-LCD panels.
The RSDS path to the source or column drivers contributes
toward lowing radiated EMI, reducing system power con-
sumption and eliminates one of the pixel busses used in typ-
ical 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 60Hz stand-
ard timing.
With the addition of a single National DS90CF364 or 564
FPD-LINK
TM
chip, the entire data path is optimized for re-
duced EMI, power consumption and width..
