DS90C2501SLB

Product Summary

The DS90C2501SLB is a transmitter with built-in scaler for LVDS display interface (LDI). The DS90C2501SLB 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.
