Geode™ CS9210 Graphics Companion
DSTN Controller
General Description
The CS9210 graphics companion is suitable for systems
that use either the GXLV or GXm processor along with the
CS5530 I/O companion; all members of the National
Semiconductor® Geode™ family of products. The
CS9210 converts the digital RGB output stream to the dig-
ital graphics input stream required by most industry stan-
dard DSTN color flat panel LCDs. It can drive all standard
DSTN flat panels up to a 1024x768 resolution. The sys-
tem connection example shows how the CS9210 inter-
faces with the rest of the system components.
Features
18-bit color support for digital pixel input
65 MHz pixel clock operation supports up to 1024x768
panels
Simultaneous CRT and DSTN display with up to 75 Hz
refresh rate
2X display refresh modes, up to 120 Hz
Supports most SVGA DSTN panels and the VESA
FPDI (Flat Panel Display Interface) Revision 1.0
Specification
TFT panel support provided by use of one connector;
allows a pass-through mode for the digital pixel input
Programmable frame rate modulation (FRM), up to 32
levels
Programmable dither, up to 16 levels
Supports EDO memory, 16-bit interface
Configuration via a serial programming interface
Low-power, 3.3V operation
144-pin LQFP (Low-profile Quad Flat Pack)
