General Description
The CH7301 is a Display controller device which accepts
a digital graphics input signal, and encodes and transmits
data through a DVI (TMDS^TM 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 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.
