Low Power Clock Oscillator

DESCRIPTION

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.

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

SPECIFICATION

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.
