LMK05318B: Is it possible to remove power to unused outputs of LMK05318B?

Hi,

Is it possible to remove power to unused outputs of LMK05318B?

The LMK05318B has 8 outputs. If only OUT_0~3 are used, is it not necessary to apply power to VDDO_4~7?

Output Supply for LVDS Clock Outputs 0 to 7 can be powered 1.8V, 2.5V or 3.3V rails. Is there any difference in the output clock depending on voltage level?

Thanks,

    Hello,

    You do not need to power the VDDO pins for the outputs you're not using.

    The output voltage supply does not affect the output clock. An LVDS output will have the following characteristics no matter what the output voltage supply is.
