ESR value is dependent upon frequency of oscillation Application Notes Crystal circuit connection The following diagram shows PI6C10806 crystal circuit connection with a parallel crystal. For the CL=18pF crystal, it is suggested to use C1=18pF, C2=18pF. C1 and C2 can be adjusted to fi ne tune to the target ppm of crystal oscillator according to different board layouts. R1=100Ω is strongly suggested. 18pF Crystal(CL=18pF) 18pF 100Ω XTAL_IN XTAL_OUT Crystal Oscillator Circuit 07-0112
