DS90UB927Q-Q1: Use Two Single channel Serializer to use as Dual Channel Serializer

Part Number: DS90UB927Q-Q1

Hello, 

Is it possible to use 2x Single channel Serializer(i.e. DS90UB927Q-Q1 ) to work as Dual channel Serializer? 

Same way is it possible to use 2x Single channel Deserializer to run a dual channel LCD?

If yes, What are the risks/Design complexity involved?

    It is possible to use two different single channel serializer to work as one dual channel serializer, but there is some added complexity. On our dual channel serializer devices, the burden of separating an input's data to go into two separate channels is on the serializer itself meaning that everything is self-contained. If you were to use two different serializer devices acting as one dual channel serializer, the burden of separating the input into two data streams would be on your processor/SoC. You would also need to verify that there is no delay difference between the two serializers as a delay would cause frames to be received incorrectly on the deserializer side.

    Similarly, it is possible to use two single channel deserializers to act as one dual channel deserializer, but the complexity will be similar to the above situation. You would need to have a processor take the two data streams and stitch them back together after going through the deserializers. Our dual channel deserializer devices simplify this by doing everything on board to make the process easier.

    Let me know if you have any other questions!

  • Hello, 

    Thanks for the Response.

    The display feed coming out of the processor is Even and Odd LVDS data lines as shown in the image. Does separation of data is needed in this case if we use 2x DS90UB927Q-Q1 Serializer for Odd and Even LVDS data respectively?

  • Howdy!

    Just so that I can understand the situation more, what is this approach attempting to address? This sort of situation is usually avoided by utilizing a dual channel device, is there a specific reason that your system would need to use two single channel devices on either end?
