FPD87370AXA
Low EMI, Low Dynamic Power VGA/XGA/WXGA TFT-LCD
Timing Controller with Reduced Swing Differential
Signaling (RSDS™) Outputs
General Description
Features
The FPD87370AXA is a timing controller that combines an
LVDS single pixel input interface with National’s Reduced
Swing Differential Signaling (RSDS™) 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™ path to the column driver contributes
toward lowering radiated EMI and reducing system dynamic
power consumption.
This single RSDS™ 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.
n Reduced Swing Differential Signalling (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 Virtual 8 bit color depth in FRC/Dithering mode
n Single narrow 9-bit differential Source Driver bus
minimizes width of Source PCB
n Ability to drive VGA, XGA and Wide XGA TFT-LCD
Systems
n Failure detect function in DE mode (Bonding Option)
n CMOS circuitry operates from a 3.0V–3.6V supply

LIFE SUPPORT POLICY
NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS
WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR
CORPORATION. As used herein:
1. Life support devices or systems are devices or systems
which, (a) are intended for surgical implant into the body, or
(b) support or sustain life, and whose failure to perform when
properly used in accordance with instructions for use
provided in the labeling, can be reasonably expected to result
in a significant injury to the user.
2. A critical component is any component of a life support
device or system whose failure to perform can be reasonably
expected to cause the failure of the life support device or
system, or to affect its safety or effectiveness.
BANNED SUBSTANCE COMPLIANCE
