EURO QUARTZ XO65 OSCILLATOR 32.768kHz Micro-miniature Clock Oscillator FEATURES Micro-miniature 3.2 x 2.5mm package Exceptionally low supply current <1.5µA Wide supply voltage range, 1.5Volts to 5.5 Volts Standby current <250nA Stable and clean CMOS output DESCRIPTION OUTLINE & DIMENSIONS 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.
