CRYSTAL CLOCK OSCILLATORS
Rev. C
LVCMOS (1.8V)
SJ-C1440 Series
PRELIMINARY
Description
The SJ-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SJ-C1440 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.
Features
• Wide frequency range– 30.0MHz to 100.0MHz
• User specified tolerance available
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Will withstand vapor phase temperatures of 253°C • Low Jitter - Wavecrest jitter characterization
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
available
• 1.8Volt operation
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• High shock resistance, to 3000g
• Metal lid electrically connected to ground to reduce • Low power consumption
EMI
• Gold plated leads
• High Q Crystal actively
tuned oscillator circuit
