    I am using Max2606 VCO for the PLL part of a FM modulator. MAX2606 has a single fixed oscillation frequency which is determined by the external inductance connected to Pin #1.

    But I need to be work this VCO within a frequency range (88MHz -108 MHz) to have more than one channel for modulation instead of single fixed frequency. How could I achieve this in MAX2606?

    Please help me.

    Download the spec from Maxim or http://www.datasheetcatalog.com

    The Vtune input can be used to tune the center frequency determined by the inductor to cover the range you desire.

    Hi. Thanks.
    I have another thing to ask. How I insert the modulating signal for the modulation?
