SM-A461-FREQ

CRYSTAL CLOCK OSCILLATORS CMOS (LVTTL Compatible) Data Sheet 0021H Rev. B HS-A460 Series Description The HS-A460 Series of quartz crystal oscillators 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 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 Electrical Connection Pin 1 7 8 14 Connection N.C. Grd & Case Output VDD • Low Jitter • High Q Crystal actively tuned oscillator circuit • Power supply decoupling internal • No internal PLL avoids cascading PLL problems • High frequencies due to proprietary design • Gold plated leads - Solder dipped leads available upon request • CMOS and TTL output levels • 3 volt operation 357 Beloit Street, P.O.
