FPD87208AXA
+2.5V Low EMI, Low Dynamic Power XGA/WXGA
TFT-LCD Timing Controller with Reduced Swing
Differential Signaling RSDS™ Outputs
General Description
The FPD87208AXA is a timing controller that combines an
LVDS single pixel input interface with National Reduced
Swing Differential Signaling (RSDS™) output driver interface
for XGA and Wide XGA resolutions. It resides on the TFT-
LCD panel and provides the data buffering and control signal
generation for XGA, and Wide XGA graphic modes. The
RSDS path to the column driver contributes toward lowering
radiated EMI and reducing system dynamic power consump-
tion.
This single RSDS bus conveys the 6-bit color data for XGA,
and three different WXGA resolutions.
Features
n Reduced Swing Differential Signaling (RSDS) digital bus
reduces dynamic power, EMI and bus-width from the
timing controller
n LVDS single pixel input interface system
n Input clock range from 25 MHz to 85 MHz
n Drives RSDS column drivers at 170 Mb/s with an
85 MHz clock (Max)
n BIST Function
n CMOS circuitry operates from a 2.25V–2.75V; 0˚C–70˚C
n 64 TQFP package with body size 10 mm x 10 mm x
1.0 mm
