CRYSTAL CLOCK OSCILLATORS
CMOS
SC-1420 Series
Data Sheet K2151
Rev. E
Description
The SC-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SC-1420 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–1.0MHz to 80.0MHz
• 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 1000g
• Low Jitter
• No internal PLL avoids cascading PLL problems
• Metal lid electrically connects to ground to reduce
EMI
• Gold plated pads
