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
