I'm working on a project that has a xtal in a similar configuration to the ones on an AVR, with load caps on either side.
The DS for the xtal states Load Capacitance as 12pf, but the circuit has a 30pf cap on each side of the xtal for c1,c2.
The DS for the chip shows C1, C2, but only states the Load Capacitance, not the values for c1, c2......
Given the LC, what should the values of c1,c2 be???
a) 1/2 of LC each
b) value of LC each
c) 2x value of LC each
See diagram below,
