I'm working on a crystal oscillator using SA602 mixer. In the datasheet Fig.6a How do I determine the values of the capacitors C1 and C2? Assuming that I want to oscillate at the fundamental freq. of the crystal.

L1,C3 elements are not required for fundamental frequency oscillator.

C1=10pF typical
C2[pF]~ 1000/F[MHz]


Have a great day,
