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

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.
