SC-C1440

SC-C1440 Series LVCMOS SC-C1440 Series Rev G Frequency Range: 70.0 MHz to 165.0 MHz Description The SC-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-C1440 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.
