gm2115/25 Preliminary Data Sheet

1. OVERVIEW

The gm2115/25 is a graphics processing IC for Liquid Crystal Display (LCD) monitors at

XGA/SXGA resolution. The gm2115/25 are pin compatible and firmware compatible to

gm5115/25 and gm3115/25. 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, 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 gm2115/25 eliminates the need for a separate LCD

monitor controller printed circuit board (PCB) from the system along with the associated

connectors and cables. Therefore, the gm2115/25 simplifies the design and reduces the cost

of LCD monitors while maintaining a high-degree of flexibility and quality.

1.1 gm2115/25 System Design Example

Figure 1 below shows a typical dual interface LCD monitor system based on the gm2115/25.

Designs based on the gm2115/25 have reduced system cost, simplified hardware and

firmware design and increased reliability because only a minimal number of components are

required in the system.
