LSC OSCILLATOR
32.768 kHz
Low Power Surface Mount Crystal Oscillator
™
actual size
DESCRIPTION
Statek’s LSC oscillator has the highest accuracy,
stability and lowest current of all STATEK surface mount
oscillators. The design consists of a STATEK crystal and
a CMOS-compatible integrated circuit. Permanent
precision tuning of the oscillator is accomplished by
laser trimming the crystal.
