SJ-2830 Series
Description
The
SJ-2830 Series
of quartz crystal oscillators provide F 100k series compatible signals in a ceramic SMD
package. Systems designers may now specify space-saving, cost-effective packaged ECL oscillators to
meet their timing requirements.
Features
• Wide frequency range–15.0MHz to 250.0MHz
• 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
• Metal lid electrically connected to ground to
reduce EMI
• Low Jitter

• F 100K series compatible output on Pin 3,
complement on Pin 1
• 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
upon request
• RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
