1. OVERVIEW

The gm5110/20 is a graphics processing IC for Liquid Crystal Display (LCD) monitors at
XGA/SXGA resolution. It provides all key IC functions required for the highest quality LCD
monitors. 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, digital color controls and an on-chip microcontroller (OCM). With this level of
integration, the gm5110/20 devices simplify and reduce the cost of LCD monitors while
maintaining a high-degree of flexibility and quality.

Figure 1 below shows a typical dual interface LCD monitor system based on the gm5110/20.
Designs based on the gm5110/20 have reduced system cost, simplified hardware and
firmware design and increased reliability because only a minimal number of components are
required in the system.
