Exceptionally low supply current <1.5µA
Wide supply voltage range, 1.5Volts to 5.5 Volts
Standby current <250nA
Stable and clean CMOS output
XO65 OSCILLATOR
32.768kHz
DESCRIPTION
XO65 oscillators are produced in a micro-miniature 3.2 x 2.5mm
package to provide 32.768kHz with very low power consumption,
typically 1.5 µA maximum at 3.3 Volts supply, less for lower supply
voltages. To conserve power the oscillator has a Standby function
implemented. The oscillator can be supplied with any voltage from
1.5 Volts to 5.5 Volts. The XO65 oscillator is an ideal choice for a
wide range of battery powered, hand held equipment.
