DS90UB927Q的使用

Steven Cai

你好，根据datasheet中的描述“The DS90UB927Q serializer, in conjunction with a DS90UB928Q or DS90UB926Q deserializer, provides a complete digital interface for concurrent transmission of high-speed video, audio, and control data for automotive display and image sensing applications.”，请问， DS90UB927Q和DS90UB926Q如何匹配应用，HOST端给出的FPD-LINK信号到DS90UB926Q能正确解出RGB信号吗

Hi Steven，

927可以直接与926/8对接，具体的应用如下图所示。

楼主你好，HOST端给出的FPD-LINK信号到DS90UB926Q能正确解出RGB信号.

Note: if the DS90UB927Q is paired with a DS90UH926Q deserializer, the devices must be configured into 18-bit mode to allow usage of GPIO pins on the DS90UH927 serializer. To enable 18-bit mode, set serializer register reg_0x12[2] = 1. 18-bit mode will be auto-loaded into the
deserializer from the serializer.

You do not need to modify any of the registers for basic operation,which means you will not use GPIO pins.
