SJ-A370 Series
Description
The SJ-A370 Series of quartz crystal oscillators are designed to survive standard wave soldering
operations without damage.
Features
• Wide frequency range–2.25MHz 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
• Metal lid electrically connected to ground to
reduce EMI
• Gold plated leads
• RoHS Compliant, Lead Free Construction
