    Hi,

    Auto Mute and Mute Level (controls 1,3) configure Auto Mute, which disables output clock if PLL loses lock. Mute Level sets the voltage the output is pulled to when PLL loses lock (in this case, Vcm).

    Setting 2 configures the output type: DIFF, CMOS, HCSL, or Disable. When choosing one of these options, the other controls functionality changes as well to match this field. In this example, since DIFF is selected, you can ignore the other fields (CMOS, HCSL) which I crossed out.

    The output control 4 is already set to LVDS so no change is needed. Control 5 doesn't do anything in this case since it only applies to HCSL and CMOS. I recommend setting it to HCSL(ExtTerm), same as the control for OUT1.

    Regards,
