GM5115

OVERVIEW

The gm5115/25 is a graphics processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA resolution. It provides all key IC functions required for image capture, processing and timing control for direct interface to the row and column drivers of the LCD panel. On-chip functions include a high-speed triple-ADC and PLL, Ultra-Reliable DVI TM receiver, a high quality zoom and shrink scaling engine, an on-screen display (OSD) controller, an on-chip microcontroller (OCM), and a programmable panel timing controller (TCON). With all these functions integrated onto a single device, the gm5115/25 eliminates the need for a printed circuit board (PCB) from the system along with the associated connectors and cables. Therefore, the gm5115/25 simplifies the design and reduces the cost of LCD monitors while maintaining a highdegree of flexibility and quality.
