OUTLINE & DIMENSIONS

DESCRIPTION

The 32.7368kHz LFXO oscillator has been designed especially for

applications requiring low power consumption, as low as 500nA. The

oscillator consists of a miniature tuning fork quartz crystal and a

CMOS/TTL compatible hybrid circuit. Each crystal is pre-qualified

before assembly by electrical tests and temperature characterization.

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

(output enabled) by an internal pull-up resistor.
