SN65DSI84-Q1: SSC_CLKIN center spread depth

Ted Xu

Hi team

SN65DSI84-Q1 supports SSC DSI CLK input function. What's the maximum center spread depth, +/-2% or +/-1%? pls double check it.

BTW, if does SN65DSI84-q1 support down spread SSC input? If yes, what's the spread depth and modulation frequency range?

Thanks

Hi Ted,

The SN65DSI84-Q1 only supports center-spread SSC for the REFCLK or DSI clock. And the spread depth supported is only 0.5 to 2% as mentioned in the datasheet.

Hi Ikram

Would you help share your comments on below concern?

What's the maximum center spread depth, +/-2% or +/-1%? pls double check it.

The description in datasheet is not clear for center-spread mode.

Thanks

Hi Ted,

The specification here is for +/- 2% for center spread. Also note that the SSC depth should be selected based on what the panel LVDS input can tolerate.
