temperature, and process variations. A series resistor, Rs, may be required if an AT strip cut crys-
tal is used. Be sure to include the device’s operating voltage and the device’s manufacturing pro-
cess when determining resistor requirements. As you can see in
the device’s internal logic is device dependent. See the applicable data sheet for device specifics.
The typical values of capacitors (C1, C2) are given in

Note 1: Recommended values of C1 and C2 are identical to the ranges tested above.
2: All resonators tested required external capacitors.

Higher capacitance increases the stability of the oscillator but also increases the
start-up time. These values are for design guidance only. Since each resonator has
its own characteristics, the user should consult the resonator manufacturer for appro-
priate values of external component or verify oscillator performance.
