HA1457

CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 0021J Rev. F HA-1450 Series Description The HA-1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the HA-1450 units with a logic “1" or open enables its pin 8 output. In the disabled mode, pin 8 presents a high impedance to the load. All units are designed to survive wave soldering operations without damage. Features Wide frequency range– 0.5MHz to 30.0MHz 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 Low Jitter Electrical Connection Pin 1 4 5 8 Connection Enable Input Grd & Case Output VDD 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 CMOS and TTL output levels RoHS Compliant, Lead Free Construction (unless solder dipped leads are supplied) Dimensions are in inches and (MM) 357 Beloit Street, P.O.
