SM-A421-FREQ

CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 9344A Rev. L HS-420 Series Description The HS-420 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–244.0Hz to 625.0kHz • 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 • Capable of driving 3TTL Loads • Low Jitter • High Q Crystal actively tuned oscillator circuit • Power supply decoupling internal • No internal PLL avoids cascading PLL problems • Gold plated leads - Solder dipped leads available upon request • RoHS Compliant, Lead Free Construction (unless solder dipped leads are supplied) 357 Beloit Street, P.O.
