1 Since this is an amplitude controlled oscillator the use of overtone oscillators is not recommended. Only use fundamental
frequency oscillators.

2 When PLL frequency modulation is active, reference frequencies less than 8MHz will distort the modulated waveform and the
effects of this on emissions is not characterized.

3 This parameter is meant for those who do not use quartz crystals or resonators, but CAN osc, in crystal mode. In that case,
Vextal – Vxtal ≥ 400mV criteria has to be met for oscillator’s comparator to produce output clock.
