ch7301c-利来app官网

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.
