| CRYSTAL CLOCK OSCILLATORS LVCMOS (1.8V) Data Sheet 0210A Rev. C SJ-C1440 Series PRELIMINARY Description The SJ-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SJ-C1440 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. Features * Wide frequency range- 30.0MHz to 100.0MHz * User specified tolerance available * Will withstand vapor phase temperatures of 253C 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 * High Q Crystal actively tuned oscillator circuit Electrical Connection Pin 1 2 3 4 Connection Enable Input Grd & Case Output VDD * High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions * Low Jitter - Wavecrest jitter characterization available * 1.8Volt operation * Power supply decoupling internal * No internal PLL avoids cascading PLL problems * Low power consumption * Gold plated leads 357 Beloit Street, P.O.
