HA-A370 Series
Description
The HA-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
• Low power consumption
• 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
