SM-A1421-FREQ

CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 9617F Rev. P HS-A1420 Series Description The HS-A1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the HS-A1420 units with a logic “1" or open enables its output. In the disabled mode, output pin 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– 40.1MHz to 70.0MHz • 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 • 3.3 Volt operation Electrical Connection Pin 1 7 8 14 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 - 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.
