    Hello, 
    

    Does the ADF4356 Vtune pin have a SPEC for sink and source currents? 
    

    I am considering a lag lead filter, but I would like to know the current capacity because there is a differential voltage in the series resistor.
    

    Best regards,
    
										

    
				How much leakage current is there in the Vtune pin of the VCO integrated in the PLL?
