SJ-A1450

www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 0001B Rev. J SJ-A1450 Series Description The SJ-A1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SJ-A1450 units with a logic “1" or open enables its pin 3 output. In the disabled mode, pin 3 presents a high impedance to the load. All units are designed to survive wave soldering operations without damage. Features Wide frequency range– 4.0MHz to 40.0MHz 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 3000g Metal lid electrically connected to ground to reduce EMI Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Input Ground Output VDD 3.3 Volt operation Low Jitter High Q Crystal actively tuned oscillator circuit Power supply decoupling internal No internal PLL avoids cascading PLL problems Low power consumption Gold plated leads TTL compatible (HCT) at specified supply voltage 357 Beloit Street, P.O.
