SURFACE-MOUNT OSCILLATORS

XO44 SERIES SMD OSCILLATOR

4 Pad SMD Package

DESCRIPTION

The Euroquartz XO44 series of surface-mount oscillators consist of a TTL

and CMOS compatible hybrid circuit coupled with a slimline UM-1quartz

hermetically sealed crystal. The oscillators provide a true SMD part that

may be supplied in a short leadtime, even for custom frequencies.

LOW FREQUENCY /LOW POWER

If you require Hz or kHz frequency oscillators with

current

consumption, for example 32.768kHz with 14mA current consumption

consider our ‘LPO’ oscillator series.

CUSTOM PARTS

The Euroquartz factory are able to produce custom frequency and

specification specification XO44 series oscillators with short leadtimes.
