DS90C2501  Product Folder

The DS90C2501 is a highly integrated scaling IC with LVDS transmitter with a scaled resolution up to SXGA+ for single pixel input. The DS90C2501 is a video controller hub designed to be compatible with Graphic Memory Controller Hub (GMCH). The input interface can be single or dual DVO port (12 pin per port). The high quality cubic zoom engine scales the input graphics into the desired/optimal output resolution up to 1400x1050 resolution. Advanced video digital signal processing provides gamma correction, and dithering for the display output. A two-wire serial interface is used to communicate with the host system. The dual high speed LVDS channels supports single pixel in-single pixel out, single pixel in-dual pixel out, and dual pixel in-dual pixel out transmission modes. The DS90C2501 complies to Open LDI standard, and can be paired up with DS90CF388 receiver or FPD8531x/FPD8731x series integrated timing controller or FPDLink LVDS receivers such as DS90CF364/DS90CF384A/DS90CF384/DS90CF384A. The LVDS output is similar to DS90C387 and DS90C387R. Thus, this transmitter can be paired up with DS90CF388, receiver of 112MHz LDI chipset or FPD-Link Receivers in non-DC Balance mode operation which provides GUI/LCD panel/mother board vendors a wide choice of inter-operation with LVDS based TFT panels.

This chip is an ideal solution to solve EMI and cable size problems for high-resolution flat panel applications. It provides a reliable industry standard interface based on LVDS technology that delivers the bandwidth needed for high-resolution panels while maximizing bit times, and keeping clock rates low to reduce EMI and shielding requirements.
