LSM OSCILLATOR
30 kHz to 400 kHz
Low Power Surface Mount Crystal Oscillator
DESCRIPTION
The LSM oscillator is an ultra-low current quartz crystal
oscillator with a typical start-up time of 500ms. The
design consists of a STATEK crystal, and a CMOS-
compatible integrated circuit. The hybrid design is
hermetically-sealed with a kovar lid in a surface mount
ceramic package. Permanent precision tuning of the
oscillator is accomplished by laser trimming the crystal.

TRISTATE/DISABLE OPTION T
FUNCTION TABLE
TRISTATE/DISABLE OPTIONS (T/N)
Statek offers two enable/disable options: T and N. The T-
version has a Tri-State output and continues oscillating
internally when the output is put into the high Z state. The
N-version does not have PIN 1 connected internally and so
has no Tri-State/Disable capability. The following table
describes the Tri-State/Disable option T.

* When PIN 1 is allowed to float, it is held high by an internal pull-up resistor.
