On frequency stability, the quartz crystal oscillator circuit is very advantageous, even the the VCXO circuit with large amount of frequency changing only changes about 1%, and the linear range of control voltage to frequency variation is not wide. Although the ceramic resonator Q value is lower than the quartz crystal oscillator, the inductive range is relatively broad, so it can get a wider frequency range, and the characteristics in the frequency stability is also better than the LC oscillator, so it is suitable for wideband FM modulator.
