WebFor the 32 MHz example, the external load capacitors are typically a bout 6.8 pF each, us ed in conjunction with a crystal that requires an 8–9 pF load capacitance. This value is used with the default internal nominal trim capacitor value (2.4 pF) and estimated stray capacitance value of 5–7 pF.
WebSo if the crystal driver has infinite impedance, the capacitive load on the crystal is 16 pF. If it has 0 impedance, the load on the crystal is 27 pF. The reality is of course somewhere in between. In reality, for normal typical microcontroller crystals somewhere around 10 MHz (factor of 2 is close enough), 22 pF caps on both sides is a good bet.
