HS-1520

www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS TTL Data Sheet 9225A Rev. U HS-1520 Series Description The HS-1520 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for bus connected systems. Supplying Pin 1 of the HS-1520 units with a logic “1" enables its output on Pin 8. In the disabled mode, Pin 8 presents a high impedance to the load. All units are resistance welded in an all metal package, offering RFI shielding, and are designed to survive standard wave soldering operations without damage. Insulated standoffs to enhance board cleaning are standard. 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 All metal, resistance weld, hermetically sealed package Electrical Connection Pin 1 7 8 14 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 - Solder dipped leads available upon request RoHS Compliant, Lead Free Construction (unless solder dipped leads are supplied) Dimensions are in inches and (MM) 357 Beloit Street, P.O.
