LSC

LSC OSCILLATOR 32.768 kHz ™ Low Power Surface Mount Crystal Oscillator DESCRIPTION actual size 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.
