Important recommendation: to obtain the performances mentioned in this specification, the serial resistance of the crystal used with this
oscillator must never exceed 120 . The crystal oscillator is guaranteed to operate at any supply voltage between 4.5 V and 5.5 V and
at any temperature between 20 C and T
The drive level is expected with a 50
series resistance values.
