General Description
The NT68665/NT68625 is a highly integrated flat panel display controller that interfaces analog, digital, and video inputs. It combines a triple ADC, a DVI compliant TMDS receiver, a digital YUV receiver, a high quality zoom and shrink engine, a multi-color on screen display (OSD) controller and many other functions in a single chip. It provides the user with a simple, flexible and cost-effective solution for various flat panel display products.
