LVCMOS
SC-C1440 Series Rev G
Frequency Range: 70.0 MHz to 165.0 MHz
Description
The SC-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SC-C1440 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—70.0 MHz to 165.0 MHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• 1.8 Volt operation
• High shock resistance, to 1000g
• High Q crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• High frequencies due to proprietary design
• Metal lid electrically connected to ground to
reduce EMI
• Gold plated pads
• RoHS Compliant, Lead Free Construction
