SJ-A1420 Series
Rev S
Frequency Range: 1.0 MHz to 80.0 MHz
Description
The SJ-A1420 Series
of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SJ-A1420 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. All units are designed to survive
standard wave soldering operations without damage.
