... Philips Semiconductors 2.5GHz low voltage fractional-N dual frequency synthesizer FUNCTIONAL DESCRIPTION Main Fractional-N divider The RFin inputs drive a pre-amplifier to provide the clock to the first divider stage. For single ended operation, the signal should be fed to one of the inputs while the other one is AC grounded. The pre-amplifier has a high input impedance, dominated by pin and pad capacitance. The circuit operates with signal levels from – ...
