HA121C

CRYSTAL CLOCK OSCILLATORS TTL Compatible Enable/Disable Data Sheet 8820B Rev. L HA-1210 Series Description The HA-1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for bus connected systems. Supplying Pin 1 of the HA-1210 units with a logic “1" enables the output on Pin 5. In the disabled mode, Pin 5 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 36MHz 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 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) Electrical Connection Pin 1 4 5 8 Connection Enable Input Grd & Case Output VCC m o c . u 4 t e Dimensions e are in inches and (MM) h s a t a .d w w w 357 Beloit Street, P.O.
