Low Power AT-Cut Clock Oscillator

FEATURES

AT-Cut crystal for excellent temperature stability

Low power consumption: 50µA typical at 15pF load

Wide supply voltage: +1.8 V to 5.0 Volts

Stability ±20ppm, 25ppm or ±30ppm

Fast start-up time

Micro-miniature 3.2mm x 2.5mm package

XO3225 OSCILLATOR

32.768kHz

OUTLINE & DIMENSIONS

DESCRIPTION

XO3225 oscillators utilise AT-Cut crystals providing much improved,

tight frequency stability as opposed to that stabiity provided by

32.768kHz oscillators using the more usual X-Cut (tuning fork)

crystals. The tight control of frequency provided by these oscillators

results in a typical variation of 52 seconds for one month of

continuous operation as against 260 seconds over the same period

for oscillators that use tuning fork crystals.Other benefits include low

supply current consumption coupled with quick start-up times.
