• 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

• Requires no external micro-controller

• External parallel ROM interface allows firmware customization

with little additional cost

• 21 general-purpose inputs/outputs (GPIO'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)

• Programmable Output Format

• Single / double wide up to XGA 75Hz output for gm5110

and up to SXGA 75Hz output for gm5120

• 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

• Stand-alone operation requires no external

ROM and no firmware development for Fast

Time to Market

• Pin and register compatible Family of Products:
