FPD87370AXA
Low EMI, Low Dynamic Power VGA/XGA/WXGA TFT-LCD
Timing Controller with Reduced Swing Differential
Signaling (RSDS
TM
) Outputs
General Description
The FPD87370AXA is a timing controller that combines an
LVDS single pixel input interface with National's Reduced
Swing Differential Signaling (RSDS
TM
) output driver interface
for VGA, XGA and Wide XGA resolutions. It resides on the
TFT-LCD panel and provides the data buffering and control
signal generation for VGA, XGA, and Wide XGA graphic
modes. The RSDS
TM
path to the column driver contributes
toward lowering radiated EMI and reducing system dynamic
power consumption.
This single RSDS
TM
bus conveys the 8-bit color data for
VGA, XGA, and Wide XGA panels at 170 Mb/s when using
VESA 60 Hz standard timing.
