SXGA LCD Monitor Controller with Integrated Analog Interface and Dual LVDS Transmitter

Genesis Microchip 

gm2121 Preliminary Data Sheet

1.2 gm2121 Features

FEATURES

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

• Integrated 8-bit triple-channel ADC / PLL

• 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

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

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

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

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)

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
