SC-1420

www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet K2151 Rev. E SC-1420 Series Description The SC-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-1420 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 tolerance available Will withstand vapor phase temperatures of 253°C for 4 minutes maximum Space-saving alternative to discrete component oscillators High shock resistance, to 1000g Low Jitter No internal PLL avoids cascading PLL problems Metal lid electrically connects to ground to reduce EMI Gold plated pads Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Ground Output VDD 357 Beloit Street, P.O.
