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.
