SC-C1420 Series
Description
The SC-C1420 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SC-C1420 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
• Wide frequency range–4.0MHz to 70.0MHz
• User specified tolerance available
• Space-saving alternative to discrete component
oscillators
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Low Jitter - Wavecrest jitter characterization
available
• 1.8 Volt operation
• High shock resistance, to 1000g
• No internal PLL avoids cascading PLL problems
• Metal lid electrically connected to ground to
reduce EMI
• Gold plated pads
• RoHS Compliant, Lead Free Construction
