Preliminary Product Brief gm2126
C2126-PBR-01A
The gm2126 device is an all-in-one image processor targeted for
the OnPanel LCD monitor market with resolutions up to SXGA.
The gm2126 leverages Genesis patented advanced imageprocessing technology and a proven integrated ADC/PLL to
provide excellent image quality in a simple and cost-effective
solution. The integrated OnPanel timing controller (TCON) is
fully programmable to interface with a wide range of
commercially available LCD panels. A dual channel RSDS
(reduced swing differential signaling) 6 or 8 bit transmitter is
provided for direct connection to column drivers with RSDS
inputs. This high level of integration reduces the number of
components, which eliminates a PCB along with its associated
connectors and cables. This reduces system cost, improves
reliability and simplifies monitor design.
Analog-Interface OnPanel SXGA LCD Controller with RSDS Transmitter
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
• Energy Spectrum Management (ESM
• 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 (“out of
range” signals)
• Moire cancellation
• Analog RGB Input Port
• Supports up to 162 MHz (SXGA 85Hz / UXGA 60Hz)
Note: resolutions and refresh rates higher than those
supported by the panel are supported as recovery
modes.
