CRYSTAL CLOCK OSCILLATORS
LVCMOS
SC-A1440 Series
Data Sheet 0007A
Rev. K
Description
The SC-A1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SC-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
• Wide frequency range–80.0MHz to 180.0MHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
