SJ-1520

www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS TTL Data Sheet 0106E Rev. D SJ-1520 Series Description The SJ-1520 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for bus connected systems. Supplying Pin 1 of the SJ-1520 units with a logic “1" enables its output on Pin 3. In the disabled mode, Pin 3 presents a high impedance to the load. Features Wide frequency range– 0.5MHz to 85.0MHz 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 VCC 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.
