The data sheet for the ADF4159 specifies AIdd, DIdd, and Ip power supply currents for Fpdf = 110 MHz.
Do these scale with the Fpfd value? Is data available for the device current usage vs. Fpfd?
Supply currents do change with Fpfd but we only characterised the supply currents at max Fpfd (110 MHz). At lower comparison frequencies the currents will decrease but we don't guarantee any numbers.
