DESCRIPTION
The 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.
FEATURES
Low power consumption
Low aging
CMOS compatible
3.3 Volt operation available
Optional Tri-State
APPLICATIONS
