XO327 OSCILLATOR
32.768kHz
Low Power Clock Oscillator
FEATURES
Micro-miniature 3.2mm x 2.5mm package
Exceptionally low supply current <1.5uA at 3.3V supply
Wide supply voltage range, 1.5 Volts to 5.5 Volts
Tristate function to conserve power
Stable and clean CMOS output
OUTLINE & DIMENSIONS
DESCRIPTION
XO327 oscillators are produced in a micro-miniature outline
package and provide 32.768kHz with low power consumption,
typically 1.5 µA at 3.3 Volts, less for lower supply voltages.
Additionally, to conserve power the oscillator has a Tristate function
implemented by default. The oscillator can be supplied with any
voltage from 1.5 Volts to 5.5 Volts. The XO327 oscillator is an ideal
choice for a wide range of battery powered, hand held equipment.
