PRELIMINARY PRODUCT BRIEF
GM5621/gm5626/gm2621/gm2626
Dual Input LCD Controller for Entry Level Applications
APPLICATI O N
Mainstream analog and dualinput XGA/SXGA LCD monitors
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(R) compliant digital receiver to deliver a high-quality solution for mainstream analog and dual input monitors. GM5621/5626 offer new Instant AutoTM 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.
