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 CH7308A supports a maximum single channel pixel rate of 140MP/s while the CH7308B supports a maximum pixel rate of 165MP/s. The minimum dual channel pixel rate is 100MP/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 monly used formats, including those specified in the Open LDI and SPWG specifications. Serialized data is outputted on three to eight differential channels.
