The CH7308B is a display controller device, which accepts

digital graphics input signals, upscales, encodes, and transmits

data through an LVDS transmitter to a LCD panel. This

device accepts one channel of RGB data over three pairs of

serial data ports.

The LVDS Transmitter includes a low jitter PLL to generate a

high frequency serialized clock and all circuitry required to

upscale, encode, serialize and transmit data. The CH7308B

supports a maximum pixel rate of 165MP/s.

The LVDS transmitter includes a panel fitting up-scaler and a

programmable dither function to support 18-bit LCD panels.

Data is encoded into commonly used formats, including those

specified in the OpenLDI and SPWG specifications.

Serialized data is outputted on three to eight differential

channels.
