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
Analog RGB Input Port
Supports up to 162MHz (SXGA 75Hz / UXGA 60Hz)
On-chip high-performance PLLs
(only a single reference crystal required)
Auto-Configuration / Auto-Detection
Automatic input format detection
Robust 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
Built in Test Pattern Generator
On-chip Microcontroller
Requires no external micro-controller
External parallel ROM interface allows
firmware customization with little additional
cost
21 general-purpose inputs/outputs (GPIO's)
and 8 general-purpose outputs (GPO’s)
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)
Low power mode (,0.15W) when no inputs are
active
Support for DDC2Bi based In-system-
Programming of Flash ROM
Built in Flexible LVDS Transmitter
Dual four channel 6/8-bit LVDS transmitter
(with high-quality dithering)
Programmable channel swapping
Programmable channel polarity
Support up to SXGA 75Hz output
