General Description
CH7303 General Description
The CH7303 is a Display Controller device which accepts a digital graphics input signal, and encodes and transmits data through a DVI link (DFP can also be supported), VGA ports (analog RGB) or a HDTV port (YPrPb). The device is able to encode the video signals and generate synchronization signals for analog HDTV interface standards and graphics standards up to UXGA. The device accepts data over one 15-bit wide variable voltage data port which supports 9 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 CH7303 is 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.
In addition to DVI encoder modes, bypass modes are included which perform color space conversion to HDTV standards and generate and insert HDTV sync signals, or output VGA style analog RGB for use as a CRT DAC.
