1
Custom specifications from 45.000 to 77.760 MHz available on an individual inquiry basis.
2
An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
3
Other temperature ranges, stabilities, and pullabilities available. See Page 56.
Note: A 0.01F bypass capacitor should be placed between V
DD
(Pin 6) and GND (Pin 3) to
minimize power supply line noise.
All specifications subject to change without notice. Rev. 02/10/03
See
