Preliminary Product Brief
gm2116
C2116-PBR-01A
The gm2116 device is an all-in-one image processor targeted for
the OnPanel LCD monitor market with resolutions up to XGA.
The gm2116 leverages Genesis patented advanced image-
processing technology and a proven integrated ADC/PLL to
provide excellent image quality in 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 connect 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.
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 crystal
Programmable gamma correction (CLUT)
RealColor controls provide sRGB compliance
PWM back light intensity control
5 Volt tolerant inputs
Energy Spectrum Management (ESM
TM
) for low EMI
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 ("out of range" signals)
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.
