DESCRIPTION
Genesis gm5766 is an all-in-one LCD monitor controller with analog (RGB), DVI and
video inputs, supporting resolutions up to UXGA in a very low pin count package. The
gm5766 leverages Genesis patented advanced image-processing technology, as well
as a proven 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, 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, 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.
