To obtain the maximum accuracy, the total circuit loading capacitance should be equal to C
XTAL
. This loading
capacitance is the effective capacitance across the crystal pins and includes the clock generating device pin
capacitance (C
FTG
), any circuit traces (C
PCB
), and any onboard discrete load capacitors (C
DISC
).
The following formula and schematic may be used to understand and calculate either the loading specification of a crystal for a
design or the additional discrete load capacitance that must be used to provide the correct load to a known load rated crystal.
