SC-A142x - NEL Frequency Controls

SC-A142x Crystal Clock Oscillators

The SC-A1420 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-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. Features • Wide frequency range–1.0MHz to 80.0MHz • User specified tol.
