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.
FEATURES
3.3V operation also available Optional Tri-State
