LMX25312265EVAL: Vtune range

Part Number: LMX25312265EVAL
We are using LMX2531LQ2265E/NOPB PLL in our FM modulation application. 
In the datasheet we are missing information on Vtune range of this PLL. So please let us know the Vtune range for this pll. Also If you have graph of Vtune vs output frequency please share here.

    Charge pump range is between 0.4 to 2V.

    For the LMX2531LQ2265E, frequency range is 2178 - 2400 MHz. The parameter to use to have a picture of what the frequency looks like across vtune is to use the Kvtune. For LMX2531LQ2265E, you have about 10-16 MHz/V, with the lower Kvtune (10 MHz/V) from the low end of the frequency range and increasing to the higher Kvtune (16 MHz/V) at the high end of the frequency range. Let us know if any additional questions. Thanks!

    Regards,
