OUTLINE & DIMENSIONS
DESCRIPTION
The Euroquartz EQXO-2000GW 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. For use in surfacemount printed circuit boards the leads are formed in 'Gull-Wing'
outline.

(frequency dependant)
Tristate Option: Output is high impedance when
'0' (<0.8 Volts) is applied to Pin 1,
(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.
