DS90UB927Q-Q1: Using ds90ub927 with iMX95 (or similar)

Part Number: DS90UB927Q-Q1

Hello!

We want to use the LVDS output of the iMX95 (NXP) to connect it to the DS90UB927 serializer, so that it eventually reaches an LCD.

To do this we follow this flow: "iMX95 -> LVDS interface -> DS90UB927 serializer -> FPD-link III interface -> DS90UB926 deserializer -> LCD".

We have the doubt in the path "iMX95 -> LVDS interface -> DS90UB927 serializer", since we know the rest of the flow works well.

Specifically, the doubt comes because the LCD is only 480x272 and the pixel clock we use is 10.8MHz. We know that this is supported by the DS90UB927 serializer (supports range [5MHz, 85MHz]), but we don't know if the iMX95 supports it. Does anyone know?

Thank you,
Daniel.

  • Hi Daniel,

    From the FPD-Link perspective, the DS90UB927-Q1 Serializer will accept the standard LVDS format, specifically:

    4 channels that would allow RGB888 (24 bits) that would eventually be LVCMOS parallel interface at the UB926 (this portion is confirmed possible).

    For the iMX95 NXP processor, this would be a question if the NXP can generate the 10.8 MHz needed at the RxCLKIN +/-, I am unable to see this from TI side.

    You may also double check the iMX95 format for using MSB / LSB as well:

    Best,
