SJA145A

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.
