OUTLINE & DIMENSIONS

DESCRIPTION

CXOX oscillators are 32.768kHz, ultra-miniature, surface mount units

packaged in a 3.40 x 2.50 x 1.12mm package. The oscillators have

been designed to provide a fast start-up time with tight frequency

stability over a wide operating temperature range of -55° to +125°C.

The design of the part ensures there is a significantly greater ability to

withstand significantly higher shock levels than standard tuning fork

crystal designs.

ENABLE/DISABLE OPTIONS

There are two Enable/Disable options available, 'E' and 'N'. The 'E'

option stops oscillating when the output is put into the High Z state.

the 'N' version does not have Pad 1 connected internally. the table

below describes the 'E' Enable/Disable option.

When Pad 1 is allowed to float it is held high by an

internal pull-up resistor.

PACKAGING OPTIONS

CXOX oscillators are available either tray packed (<250pcs) or tape

and reel (>250 pieces).

12mm tape, 178mm or 330mm reels (EIA 418).
