Description
GM5766
1
Description
The GM5766 is an all-in-one LCD monitor controller with analog (RGB), DVI and video inputs, supporting resolutions up to UXGA/WSXGA+ in a very low pin count package. The GM5766 leverages advanced image-processing technology. As well, it has an integrated ADC/PLL and an Ultra-Reliable DVI compliant digital receiver to deliver a high-quality solution for mainstream dual-input monitors. The GM5766 also includes an ITU656 video input port with color space converter that makes it an attractive solution for low cost MFM and TV applications. The output section contains a 24-bit TTL output interface and a dual channel LVDS/RSDS transmitter for direct interfacing of commercially available LVDS and RSDS LCD panel modules. In addition, the GM5766 includes an integrated x86 OCM with SPI compatible interface, advanced color control features, a multicolor proportional font OSD engine, and a number of system I/O components. Along with the high quality and reliability, the GM5766 also provides a very low cost system design by reducing the number of system components and the capability of deploying on a small size two layer PCB.
