LSC OSCILLATOR
30 kHZ to 400 kHz
Low Power Surface Mount Crystal Oscillator
DESCRIPTION
The LSC oscillator is designed especially for
applications requiring low power consumption. The
design consists of a Statek miniature Tuning Fork quartz
crystal and a CMOS compatible integrated circuit in a
ceramic package.

FUNCTION TABLE
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.
