Product Brief
gm3110
The gm3110 device is an all-in-one image processor targeted on
LCD monitors with resolutions up to XGA (1024x768). The
gm3110 leverages Genesis patented advanced image-
processing technology as well a Genesis proprietary Ultra-
Reliable DVI-compliant digital receiver to provide excellent
image quality. In addition, an integrated microcontroller is
provided. These features provide a very simple and cost-
effective solution for high-end, digital interface LCD monitors.
FEATURES
Zoom (from VGA) and shrink (from UXGA) scaling
Integrated Ultra-Reliable DVI 1.0-compliant receiver
High-Bandwidth Digital Content Protection (HDCP)
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
RealRecovery function provides full color recovery
image for refresh rates higher than those supported by
the LCD panel
Moire cancellation
Ultra-Reliable DVI Compliant Input Port
Operating up to 165 MHz (up to UXGA 60Hz)
Direct connect to all DVI compliant digital transmitters
High-bandwidth Digital Content Protection (HDCP)
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
