GM5621 Dual input LCD controller for entry-level applications

Genesis GM5621 and GM5626 are all-in-one dual input LCD monitor controllers supporting resolutions up to SXGA/WXGA, 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 highquality 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 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 is a pin-compatible analog derivative product with integrated ADC/PLL, but no DVI receiver.
