Part Number: SN65DSI83

The datasheet of SN65DSI83 mentioned the chip supports spread of the LVDS CLK(SSC_CLKIN), but there is no register can set the SSC in the datasheet, could you please advise how to enable SSC and how to set the center spread depth?

    Hey Zhirong,

    The clocking for the DSI83 is determined by the output panel you are displaying to. Please have a look at the DSI Tuner Tool which will help you determine the clock requirements for your system. Once you have your clock frequency determined, this will be the center of your SSC clock as well. the 0.5% to 2% deviation can be calculated from the SSC center. 

    SSC is by default enabled.

    Here is the DSI Tuner Tool:
