SJ-1420 Series
Data Sheet 0010F
Rev. J
Description
The SJ-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SJ-1420 units with a logic “1" or open enables its pin 3
output. In the disabled mode, pin 3 presents a high impedance to the load. All units are designed to
survive standard wave soldering operations without damage.
Features
• Wide frequency range– 40.1MHz to 80MHz
• 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
• High Q Crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• Low power consumption
• Gold plated leads
• RoHS Compliant, Lead Free Construction
