CRYSTAL CLOCK OSCILLATORS
LVCMOS
SC-B1440 Series
Data Sheet 0540B
Rev. -
Description
The SC-B1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SC-B1440 units with a logic â1" or open enables
its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load.
Features
⢠Wide frequency rangeâ220.0MHz to 250.0MHz
(Contact factory for other frequencies)
⢠User specified tolerance available
⢠Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
⢠Space-saving alternative to discrete component
oscillators
⢠2.5 Volt operation
