Description

The CH7301 is a Display controller device which accepts a digital graphics input signal, and encodes and transmits data through a DVI (TMDSTM link) or DFP (Digital flat panel) can also be supported. The device accepts data over one 12-bit wide variable voltage data port which supports four different RGB data formats.

The DVI processor CH7301A includes a low jitter PLL for generation of the high frequency serialize clock, and all circuitry required to encode, serialize and transmit data. The CH7301 comes in versions able to drive a DFP display at a pixel rate of up to 165MHz, supporting UXGA resolution displays. No scaling of input data is performed on the data output to the DVI device.
