CMOS
HS-370 Series
Description
The HS-370 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 85.0MHz
• 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
• 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
