CRYSTAL CLOCK OSCILLATORS Data Sheet 9617E Rev. N CMOS HS-A370 Series Description The HS-A370 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. Low voltage operation (3.3V). Features • Wide frequency range–0.5MHz 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 • 3.3 volt operation • Low Jitter • TTL compatible (HCT) at specified supply voltage • High Q Crystal actively tuned oscillator circuit • Power supply decoupling internal • No internal PLL avoids cascading PLL problems • High frequencies due to proprietary design • All metal, resistance weld, hermetically sealed package • Gold plated leads - Solder dipped leads available upon request • RoHS Compliant, Lead Free Construction (unless solder dipped leads are supplied) Electrical Connection Pin 1 7 8 14 Connection N.C.
