EQXO-2000 Series
8 pin Dual-in-Line Clock Ocillators
OSCILLATORS
DESCRIPTION
The Euroquartz EQXO-2000 series of 8 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.

(internal pull-up).
Disable time = 150ns max.
* The frequency stability parameter is inclusive of frequency adjustment
at 25°C and any variations due to load change, ageing, supply voltage
change (±10%) and variations attributable to shock and vibration.

EXTENDED INDUSTRIAL TEMPERATURE RANGE
The part previously specified by Euroquartz Ltd as EQXO-2050UM
or EQXO-2100UM has been superceeded by the extended-
industrial temperature range part EQXO-2***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-2000BM series.
PART NUMBER GENERATION
EQXO-2000 series oscillator part numbers are derived as follows:
