SJ-A142C-FREQ

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.
