EURO QUARTZ XO64 OSCILLATOR 32.768kHz Low Power Clock Oscillator FEATURES · · · · · Micro-miniature 6.5mm x 4.0mm package Exceptionally low supply current <5uA Wide supply voltage range, 1.5Volts to 6.0 Volts Tristate function to conserve power Stable and clean CMOS output DESCRIPTION OUTLINE & DIMENSIONS XO64 oscillators are produced in a micro-miniature package and provide 32.768kHz with low power consumption, typically 5 micro Amps maximum at 3.3 Volts, even 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 6.0 Volts. The XO64 oscillator is an ideal choice for a wide range of battery powered, hand held equipment.

See note** 500ms max. (3.3 Volts supply at 25°C) NOTES * Frequency stability parameter includes calibration tolerance at 25°C, temperature variations, frequency change due to shock and vibration and ±10% supply voltage variation. ** Output (Pad 3) is active if not connected or a voltage to Pad 1 is ‘HIGH’. Output is high impedance when ‘LOW’ or Ground is applied to Pad 1.
