1.2 gm2115/25 Features

gm2115/25 Preliminary Data Sheet

FEATURES

• Zoom (from VGA) and shrink (from UXGA) scaling

• 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 OnPanel Family:
