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 commonly used formats, including those specified in the OpenLDI and SPWG specifications.
Serialized data is outputted on three to eight differential channels.
