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
).
