General Description

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.
