QUARTZ

DESCRIPTION

CXOL oscillators are ultra-miniature (32. x 1.5mm), ultra-low current

quartz crystal oscillators with a typical start-up time of 200ms.

Hermetically sealed in a highy reliable ceramic housing, these

oscdillators are available over a wide range of input voltages (1.2V ~

5.0V).

There are two Enable/Disable options available, 'T' and 'N'. The 'T'

version has a Tri-State output and continues oscillating internally

when the output is put into a high Z state. The 'N' version does not

have PAD 3 connected internally and so has no Tri-State capability.

The table below describes the Tri-State option 'T':
