DESCRIPTION
Genesis gm5621 and gm5626 are all-in-one dual input LCD monitor controllers
supporting resolutions up to SXGA, available in a very low pin count package.
gm5621/5626 leverage 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 analog and dual
input monitors. gm5621/5626 offer new Instant Auto™ technology, which provides
fast and accurate image alignment for both static and moving images of the analog
input signal. gm5621 includes an on-chip, industry standard, dual channel LVDS
transmitter and a TCON, and gm5626 includes a dual channel RSDS transmitter
for direct interfacing of commercially available LVDS/RSDS LCD panel modules. In
addition, gm5621/5626 include an integrated X86 OCM with SPI compatible
interface, a multicolor proportional font OSD engine, a programmable coefficient
scaling engine, dual channel Schmitt and Reset circuitry. Along with the high
quality and reliability, gm5621/5626 also provide a very low cost system design by
reducing the number of components and the reduction in the board size.
gm2621/gm2626 are pin-compatible analog derivative products with integrated
ADC/PLL, but no DVI receiver.
