CMOS
SJ-1420 Series
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 253C
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
