OSCILLATORS
EURO QUARTZ
EQXO-1000 Series
14 pin Dual-in-Line Clock Ocillators
DESCRIPTION
The Euroquartz EQXO-1000 series of 14 pin dual-in-line oscillators
consist of a Universal, TTL and CMOS compatible hybrid substrate and
quartz crystal in a hermetically-sealed package. The oscillators
provide a proven and reliable source of clock signals with low unit
cost.

PART NUMBER GENERATION
EQXO-1000 series oscillator part numbers are derived as follows:
Example: 10.000MHz EQXO-1050UIET3:
10.000MHz EQXO-1050 U IE T 3
Frequency
Model number
(see table above)
U - Universal output
C - Commercial temperature
I - Industrial temperature
IE - Extended Industrial temperature
T - Tristate function (option)
Blank -
5.0 Volts supply
3 -
3.3 Volts supply
The part previously specified by Euroquartz Ltd as EQXO-1050UM
or EQXO-1100UM has been superceeded by the extended-
industrial temperature range part EQXO-1***UIE. This part will
perform within specification over the temperature range of -55° to
+105°C. Should a full military temperature range oscillator be
required see specification for EQXO-1000BM series.
