描述

The CH7301C is a display controller device which accepts a digital graphics input signal, and encodes and transmits data through a DVI or DFP (Digital flat panel). The device accepts data over one 12-bit wide variable voltage data port which supports different data formats including RGB and YCrCb.

The DVI processor includes a low jitter PLL for generation of the high frequency serialized clock, and all circuitry required to encode, serialize and transmit data. The CH7301C 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. See Figure 1 for the functional block diagram of the CH7301C.

Color space conversion from YCrCb to RGB is supported in both DVI and VGA bypass modes.
