Series
Size, mm
9 x 14
I/O
4 J Lead
Supply Voltage
3.3V / 5V
LVCMOS
SJ-A1440 Series Rev P
Frequency Range: 10.0 MHz to 250.0 MHz
Description
The SJ-A1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SJ-A1440 units with a logic “1” or open enables its Pin 3
output. In the disable mode, Pin 3 presents a high impedance to the load.
Features
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Low jitter - Wavecrest jitter characterization avail-
able
• Wide frequency range—10.0 MHz to 250.0 MHz
• 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
• 3.3 Volt operation
• 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
