STABILITY & PART NUMBER SELECTION
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.

EXAMPLE:
16.000MHz XO44050UCT3
Frequency -
Model No: -
(See table above)
Stability
025 = ±25ppm
050 = ±50ppm
100 = ±100ppm
U = CMOS/TTL o/p
Temperature Range
C = 0°~+70°C
I = -40°~+85°C
T = Tristate
Blank = 5.0 Volts Supply
3 =
3.3 Volts Supply
LOW FREQUENCY /LOW POWER
If you require Hz or kHz frequency oscillators with mA 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.
