3. 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.

The NT68665/NT68625 operates at frequencies up to 165MHz, suitable for LCD monitor up to SXGA

resolution. By using alternate sampling technology, the supported analog input resolution can be

extended to UXGA mode.

The NT68665/NT68625 also has a built-in noise reduction function to provide more stable video

quality, spread spectrum to provide low EMI solution, sRGB for video color space convert and post

pattern for manufacture test.

The display provided multi-interface with timing controller or without timing controller. With timing

controller provided single/double pixel clock RSDS interface; without timing controller provide

single/double pixel clock LVDS interface.

In addition, NT68665/NT68625 includes an integrated 8-Bit Microcontroller (MCU). It contains an 8-bit

8031 micro-controller, on-chip 64K/128K bytes flash-type program ROM, 1,280-bytes internal data

memory, four 7-bit resolution A/D Converter, 10-channel 8-bit resolution PWM DAC, two16-bit

timer/counters, and a UART. Except those, it has two-channel hardware DDC solution, and VESA

2Bi/2B+ master/slave I2C bus interface.
