GMZAN3 Datasheet, PDF (8/53 Pages) List of Unclassifed Manufacturers – XGA ALALOG INTERFACE LCD MONITOR CONTROLLER

gmZAN3 Preliminary Data Sheet
1 Overview
The gmZAN3 is a graphics processing IC for Liquid Crystal Display (LCD) monitors at XGA 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, a high quality zoom and shrink scaling engine, an on-screen display
(OSD) controller and digital color controls.
The gmZAN3 is provided with two versions;
• gmZAN3T with 48-bit TTL output and
• gmZAN3L with industry standard single four channel LVDS transmitter for direct connect to LCD
panels with LVDS interface.
With this level of integration, the gmZAN3 devices simplify and reduce the cost of LCD monitors while
maintaining a high-degree of flexibility and quality.
1.1 gmZAN3 System Design Examples
Figure 1 below shows a typical analog interface LCD monitor system based on the gmZAN3. The
gmZAN3 reduces system cost, simplifies hardware and firmware design and increased reliability because
only a minimal number of components are required in the system.
