SJ-1420

www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 0010F Rev. J SJ-1420 Series Description The SJ-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SJ-1420 units with a logic “1" or open enables its pin 3 output. In the disabled mode, pin 3 presents a high impedance to the load. All units are designed to survive standard wave soldering operations without damage. Features Wide frequency range– 40.1MHz to 80MHz User specified tolerance available Will withstand vapor phase temperatures of 253°C for 4 minutes maximum Space-saving alternative to discrete component oscillators High shock resistance, to 3000g Metal lid electrically connected to ground to reduce EMI Electrical Connection Pin 1 2 3 4 Connection Enable Input Grd & Case Output VDD Low Jitter High Q Crystal actively tuned oscillator circuit Power supply decoupling internal No internal PLL avoids cascading PLL problems Low power consumption Gold plated leads RoHS Compliant, Lead Free Construction 357 Beloit Street, P.O.
