Integrated 8-bit triple-channel ADC / PLL  
 
On-chip programmable OnPanel timing controller 
 
Embedded microcontroller with parallel ROM interface
 
On-chip versatile OSD engine 
 
All system clocks synthesized from a single external crystal 
 
Programmable gamma correction (CLUT) 
 
RealColor controls provide sRGB compliance 
 
PWM back light intensity control 
 
5 Volt tolerant inputs 
 
Low EMI and power saving features 
 
High-Quality Advanced Scaling 
 
Fully programmable zoom ratios 
 
High-quality shrink capability from UXGA resolution 
 
Real Recovery function provides full color recovery 
image for refresh rates higher than those supported by 
the LCD panel 
 
Moire cancellation 
 
Analog RGB Input Port 
 
Supports up to 162.5MHz (SXGA 75Hz / UXGA 60Hz) 
 
On-chip high-performance PLLs 
(only a single reference crystal required) 
 
Auto-Configuration / Auto-Detection 
 
Input format detection 
 
Phase and image positioning 
 
RealColor Technology 
 
Digital brightness and contrast controls 
 
TV color controls including hue and saturation controls 
 
Flesh-tone adjustment 
 
Full color matrix allows end-users to experience the 
same colors as viewed on CRTs and other displays 
(e.g. sRGB compliance) 
 
On-chip OSD Controller 
 
On-chip RAM for downloadable menus 
 
1, 2 and 4-bit per pixel character cells 
 
Horizontal and vertical stretch of OSD menus 
 
Blinking, transparency and blending 
 
On-chip Microcontroller 
 
Requires no external micro-controller 
 
External parallel ROM interface allows firmware customization 
with little additional cost 
 
23 general-purpose inputs/outputs (GPIOs) available for 
managing system devices (keypad, back-light, NVRAM, etc) 
 
Industry-standard firmware embedded on-chip, requires no 
external ROM (configuration settings stored in NVRAM) 
 
Built-in OnPanel Timing Controller 
 
Eliminates the need for an external panel timing controller 
(TCON) device, thereby reducing system cost 
 
Direct connect to commercial row/column driver ICs (supports 
dual-bus / dual-port and dual-bus / single-port) 
 
Low EMI and power saving features include frame, line and in-line 
inversion, blanking, data staggering and slew rate control. 
 
Programmable Output Format 
 
Single / double wide up to XGA/SXGA 75Hz output 
 
Pin swap, odd / even swap and red / blue group swap of 
RGB outputs for flexibility in board layout 
 
Support for 8 or 6-bit panels (with high-quality dithering) 
 
Highly Integrated System-on-a-Chip 
Reduces Component Count for 
Highly Cost 
Effective Solution
 
Standalone
 operation requires no external 
ROM and no firmware development for 
Fast 
Time to Market
 
Pin and register compatible
