ch7308b-利来app官网

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.
